Another turn metric that was used some time ago: Axis/Axial Turn Metric (ATM). It was like STM, but only cared about the axis of rotation, and when that axis changed, a move was added. Example: R L is 1 move, R F is 2, R F B L R D is four
I recently just got into cubing and I just wanted to explain what they mean by 2-gen. In abstract algebra, there are mathematical structures called groups, which are sets with a binary operation (addition, subtraction) with a list of axioms that the set of elements has to satisfy. A generating set is a subset of the elements in a group when every possible distinct combination of binary operation between elements is performed, creates a subgroup of the group. An n-gen is simply an algorithm (product of elements of a subgroup) that can be generated by n distinct moves (elements). This seems arbitrary until we realize that the Rubik’s cube forms a group and our algorithms are elements in a subgroup of the Rubik’s cube. A 2-gen is an algorithm that can be generated by two basic moves (sexy move is generated by R and U and their inverses for example so it’s a 2-gen)
@@adilghaznavi3948 it's not general enough, which is ironic because there is no addition and subtraction in this example a better explanation of a binary operation is something with two inputs and one output in this context, that is move composition
Yet another novice cuber here just letting know how helpful your channel is. I've gone from a 1m30 average to under 40secs average in two weeks by following your tips! 👍👍👍
Ooh! i know the generator thing! so in Group Theory, a generator set of a group is a minimal subgroup of elements (in this case, moves) such that every element of the group can be expressed as a combination of those moves. So here. N-gen is just talking about the order of the generator set. so, for example, the subgroup {R,R2,R',-} ('-' being the null move) can be generated by R: (R, RR, RRR, RRRR). it can also be generated by R' , but not by R2. group theory is so much fun!
3:22 The mathematical word for that sort of averaging is _truncated mean_ where the extremes are eliminated and the mean is computed for the remaining results.
well if u want just one sub 30 solve, look for cubehead's lucky scramble part 1 video. it had an easy scramble with 19 move cfop solution. I average around 35-45 seconds(sometimes i do get 30-35 and rarely i have got 25-30), but i did that scramble in 12 seconds
re: 2-gen The term "generator" comes from group theory, and it's not really "complicated math stuff". You already explained it - an algorithm generated by some sequence of two face turns. A rubik's cube can be described as the "group" of all scrambles. Since every scramble can be decomposed into a sequence the six face turns, we say that the group is "generated" by . This group has subgroups like (the group of any scramble that only has opposite colors on a face, which is generated by half terms) and (the group of any algorithm generated by any sequence of two adjacent turns. A "2-gen").
How do I transition from intuitive F2L to full F2L? I'm averaging around 20 seconds and the bulk of my solve time (~12 seconds) is F2L, and I'd like to work on bringing it down. I understand the importance of look ahead but there seems to be so many algorithms for F2L cases and I have no clue which ones are worth learning.
+Matthew Pharr an algorithm is worth learning for F2L if: - it can be executed faster than what you currently do - it doesn't hinder look ahead very much (such as using too much R2 or wide moves) Both of those must be true. Just start by picking an algorithm that solves a case you commonly run into. I find that one of the most important algs is R' F R F' R' U' R. Then once you have done it a few times in speedsolves, you'll remember it and you can learn a new one.
Ok, so two months later I'm coming back to this, and seeing shapes I now recognise have totally different names. I called them things like - T is "a bug with antennaes", L is a blob of algae in a lake or pool, (and it's facing you at the bottom cause it's trying to touch you before you can get away), Pi is a turtle swimming by in front of you.
could you like tell or show all the algorithms and finger tricks you have learnt and use currently in a video you could give links to the videos on the stuff you have already gone through its like everything you need to know to become as good as you pls i big fan
+LEGEND 7 i have PLL and I'm thinking of remaking it. I'm already filming OLL algs, and I show almost all of my F2L algs in my "these F2L cases" videos

0:53 this helped me so much i dont mean to brag, but my tps is very fast, but i ALWAYS pause after inserting an f2l pair or doing an alg, this made all my times average 35 sec. i just started turning slowly, and i was able to use look ahead, and guess what, i average 30 secs now. thank you so much j perm!
There's also an ATM. Axial turn metric. I assume it means that something like M+R counts as a single move. Unfortunately, it won't make your cube spit out money for some reason.
Idk if you ever did find out the 2-gen "2 generator" thing, but it comes from the idea of a "finitely generated" group in Group Theory. So I'm gonna skip over the definition of group cuz I don't think it matters here, but to get an idea of a finitely generated group, we can use a clock as an example of a 1-generator group: If we only count the hour marks 1,2,3,4,5,6,7,8,9,10,11,12 as the set of possibilities, there are a few things we can see from this -- namely, all these elements can be considered "actions" (for example the number 1 can be interpreted as moving 1 hour forward), and that the action corresponding to 12 (i.e.: moving 12 hours forward) will always return to the number it started on (we call this the identity element). But even more important is that you can take 1 element and it's corresponding action, and just repeatedly use it to create all the other elements, namely, moving forward 1 hour until you get all 12 hours (so do 5, 7, and 11, but the key is that such a number *exists*) -- and this becomes a group generated by 1 element. So why does this matter to Rubik's cubes? Because a Rubiks cube can be interpreted as a finitely generated group with 4 quintillion elements (corresponding to all the possible positions it can be in), and (assuming all centers remain in place) only 6 generators: R,L,U,D,F, and B (ofc also their inverses R',L',U',D',F', and B' depending on how you wanna define things). So what does all that mean? It means that you can reach all possible combinations (elements) with some series of these 6 turns (actions) and no need for others. Which -- in the end -- feels pretty obvious, and is just fancy language for something that seems pretty mundane. The only reason it's useful is because we can then generalize it to things which don't have obvious turn and repeat structures that display these properties, which is beyond the scope of this comment. Anyway, if you restrict the possibility space of a rubiks cube to only using R and U as generators, you then get a new group that is generated by 2 elements -- all the possible positions that can be reached by only using some series of R and U (and by extension R2, R', U2, and U' since they can be expressed in terms of R and U). TL;DR: "generators" in Group Theory are just a way to generalize the properties of an object like a rubiks cube in a manner that's got maybe a bit too much jargon.
Note: the "elements as actions" in the clock is kinda a shorthand, the standard definition of groups entails a function (usually called addition) f(m,n) which takes m and n as arguments and produces an output within the group. The thing is, you can use this to create a series of functions f_n(m)=f(m,n), which can be interpreted as "applying" n to m without changing any of the underlying structure. As such, you can interpret all elements n as f_n(0)=f(0,n)=n (0 being the identity element here). This might seem weird at first, but is fairly standard, and is the basis for the category theory interpretation of a group as well as why we normally name elements after what moves it takes to get there, but a big part of the reason for this is that "adding" in contexts of a physical object representative can be seen as "apply this, then apply this", and as such you can often pick a reference frame for the identity from multiple elements so long as it corresponds to 0 actions (basically the same as saying any position of the cubes *could* be the goal of the solve, we just choose the one that feels nice, but the math doesn't care)
THANKS for clearing up COLL vs OLLCP! Ran into a guy at a comp who knew OLLCP but had never heard of COLL, and I left that conversation very confused...
I didn't know that you take off the worst and best time for an average cause I was like "oh well, everyone with a world record single obviously has the wolrd record average"
Not sure, but I think the gen in 2-gen and 3-gen has to do with generating algorithms. For example, if you generate an optimal T Perm it would have a lot of B and D moves. But you can also generate it with 3 moves or 3 gen. I think that's what it means.
Fun fact: the "average" used in speedcubing competitions is called a truncated or trimmed mean in statistics. In particular, it is a 20% truncated/trimmed mean, because you drop the 20% (1/5) best times and the 20% (1/5) worst times, then take the arithmetic mean of the rest. Also not something speedcubers invented, but anyway...
I just learned the Rubik’s cube last week. I have my freashman year tests going, and instead of studying, I decided to learn some speedcube methods. This is where it gets a bit weird. I tried CFOP. Couldn’t do it cause OLL/PLL was wayyy too confusing. Tried zz. Same problem. But then I tried roux. My average went from 1:22 to 0:20. I know it’s not a lot, but still. One week.
Can anyone help me, im learning 4x4 yau, but every time i get to OLL its an unsolvable case (not parity) on the yellow side, one yellow edge if flipped but the one right next to it isn't, can anyone help?
Htm = half turn metric. Html = hypertext markup language(just to format elements in webpages. Not a coding language) One thing I can relate to in this video
The term was coined by Lars Petrus for his method. Sune is a male name in Sweden and is an iron age form for 'the son'; in modern Swedish that is 'sonen'. It is pronounced "soon-eh" ([suːnɛ]), but in cubing it has become far more common to be pronounced "soon" ([suːn]).
COLL: For Intermediate CFOP OLLCP: For Advanced CFOP Cuz in the intermediate method you first solve the cross at the U layer (with 6 moves exactly) and then you use one of the 7 OLLs that stands for the cross solved. But in the advanced method you solve both at the same time

Hello, is it true that a beginner should start with cheaper cubes instead of premium cubes because it ruins their finger tricks? what cube did you use when you begin speedcubing? was it the best available in the market at the time?
+River Capulet I think it's untrue but that's just my opinion. I used a standard Rubik's cube (which can't corner cut) until I was averaging around 27. But that's irrelevant nowadays since all the budget cubes are as good as the best cubes were back then. The Dayan guhong was the best cube when I started. Today the difference between cheap/best cube is not that big, and you get corner cutting and easy turning on any cube. Getting a budget cube is probably better as a beginner simply because by the time you'll really benefit from a $50 cube, there will probably be a new and better one available. And i think it's good to have a decent cube and not a dollar store cube because you can practice good finger tricks on it.
+Paris Dorn Oh yeah! it most commonly refers to the last move of the solve, which is why I said it like that. but you're right, I should have covered all the applications
generator means the matrices that when multiplied, generates a lie algebra. In cubing terms it is the two moves that are used to make any algs with the two moves COLL - Corners of last layer?
+Ariana Grande COLL was defined as corners +OLL when I checked the wiki for making this video. a few hours after uploading the video, someone changed it to corners of the last layer on the wiki.

Sourabh Agarwal Antoine Cantin has 20+ vids on OH ll algs
+George Scholey thanks
+Sourabh Agarwal I'll make one for PLL, but my OLLs are not very good.
+J Perm thanks that would be a lot of help !
You use COLL in OH, right?
Fun fact: the "average" used in speedcubing competitions is called a truncated or trimmed mean in statistics. In particular, it is a 20% truncated/trimmed mean, because you drop the 20% (1/5) best times and the 20% (1/5) worst times, then take the arithmetic mean of the rest. Also not something speedcubers invented, but anyway...
Okay, maybe only a "fun" fact if you're a nerd like me. :P
thanks for the info! I should have fully done my research :P
what do you MEAN?
I started a 6x6 as this video started and finished perfectly in time with the end
AUF= Adjust U face ❌
AUF= Adjust Ur face✔️
*self esteem decreases*
I would say gen is very popular for stuff like Roux
+TheJor27 oh yeah forgot about that.
TPS
My Brain: Third Person Shooter
J Perm: Turns Per Second
the Sexy alg i use it to put the corners on the last layer ,
and the Sune alg i use it to correct the cross colours
1:25 he's faster than me even if he's not trying
I just learned the Rubik’s cube last week. I have my freashman year tests going, and instead of studying, I decided to learn some speedcube methods. This is where it gets a bit weird. I tried CFOP. Couldn’t do it cause OLL/PLL was wayyy too confusing. Tried zz. Same problem. But then I tried roux. My average went from 1:22 to 0:20. I know it’s not a lot, but still. One week.
I want more!!!!
notification squaaddd
Kjell Yesss
eyyy. Ik ben opeens beter met ortega in 2x2 lol 4.4 gemiddled ongeveer lol
Kjell nuce
Oli4x4 jajajaja
Mika Smulders
Mikaaaa
Can anyone help me, im learning 4x4 yau, but every time i get to OLL its an unsolvable case (not parity) on the yellow side, one yellow edge if flipped but the one right next to it isn't, can anyone help?
Elliox oh yeah...... lol forgot that was a thing thx
At 1:57 you can do this R U’ L’ U R’ U’ L
Htm = half turn metric.
Html = hypertext markup language(just to format elements in webpages. Not a coding language)
One thing I can relate to in this video
This video is weilong
Sorry
Aolong is it?
@@fgvcosmic6752 it's suuuulong
I have been cubing for over 3 years and did not know the whole metrics thing, except for the M vs. L' and R.
For the 1 % of people who see this I just want to let you know that
God loves you ❤️♥️❤️♥️❤️
"Sune" is the Japanese (or Chinese) word for "five", it's because you see 5 yellow pieces (without center).
+Sa Me LOL
Suuney: R,U,R',U,R,U2,R'
The term was coined by Lars Petrus for his method. Sune is a male name in Sweden and is an iron age form for 'the son'; in modern Swedish that is 'sonen'. It is pronounced "soon-eh" ([suːnɛ]), but in cubing it has become far more common to be pronounced "soon" ([suːn]).
COLL: For Intermediate CFOP
OLLCP: For Advanced CFOP
Cuz in the intermediate method you first solve the cross at the U layer (with 6 moves exactly) and then you use one of the 7 OLLs that stands for the cross solved. But in the advanced method you solve both at the same time
This is a much needed video since there are so many troll videos that are jokes.
+Carson Moore 30 cubing definitions by colorfulpockets is certainly not a joke
About generators: the algorithm can be "generated" only by turning the two layers,
R, U,and counter-clockwise R' and U'
Me: Does TeamBLD
Partner: Okay, do a Soonay
Me: ????
Partner: You have to be kidding
1:19 ''it would be better off for me to turn slower''
me: takes in his advice and uses it in his solves
also me: gets times 10 seconds slower
i think i'm getting scammed
jk i love jperm's videos
4:02 Jperm with the math skills😎
j perm you are now 20k subs i am here when you are 2k nice channel and nice video keep it up
+Noobishere -_- thanks :)
This video is very helpful I didnt know what 2 gen was and I've tried looking what 2 gen was but someone had to comment a comment saying what 2 gen is
Scan you solve a cube if the corners are twisted ? I’m trying to use a solver because I’m into pyraminxs more and wanted to solve my cube but can solve it
So with tps, do we stop the timer once we’ve finished the Alg? Or when we finished the alg plus solve the cube
All names came from Lara Petrus, in his site he says the names are from his friends, Suen, Bruno, Bernard, Bob, etc
1:55- seeing those blocks, i think a back anti sune should be done.
The only person ever with a good first vid
if you sometimes need to auf in cfop then why isnt it called cfopa?
1:17
Its the mf3rs right? I think so because it has some weird beating-like-sound
I am not a begginer but some of this i still didn't know like coll vs ollcp the metrics, i like how you used the average from the last critique vid (20.79)
+ricky golfer haha you're the first to notice!
lol thanks, speaking of solve critiques, can you check your facebook messages please
1:09 that snap
good timing i was literally going to search or request for a video like this
@J Perm how do you figure out whether to insert the pair a normal way or use sledgehammer
The sound quality in this video is very good. Idk if you worked on it or is it just appearing to me aa good. Haha
+Yash Mittal I didn't do anything different haha
Hello, is it true that a beginner should start with cheaper cubes instead of premium cubes because it ruins their finger tricks? what cube did you use when you begin speedcubing? was it the best available in the market at the time?
+River Capulet I think it's untrue but that's just my opinion.
I used a standard Rubik's cube (which can't corner cut) until I was averaging around 27. But that's irrelevant nowadays since all the budget cubes are as good as the best cubes were back then. The Dayan guhong was the best cube when I started.
Today the difference between cheap/best cube is not that big, and you get corner cutting and easy turning on any cube. Getting a budget cube is probably better as a beginner simply because by the time you'll really benefit from a $50 cube, there will probably be a new and better one available.
And i think it's good to have a decent cube and not a dollar store cube because you can practice good finger tricks on it.
Thanks for your answer :)
AUF doesn't specifically apply to the last move of the whole solve. It can also be used to show a move after an f2l pair for example
+Paris Dorn Oh yeah! it most commonly refers to the last move of the solve, which is why I said it like that. but you're right, I should have covered all the applications
I think moves should be counted as 1 move if they can be written down as 1 move. M2 is 1 move then
Well you could write sune as S and antisune as S' but I don't think that makes them one move
is it better to memorize coll and ollcp, or just regular oll and pll?
generator means the matrices that when multiplied, generates a lie algebra.
In cubing terms it is the two moves that are used to make any algs with the two moves
COLL - Corners of last layer?
+Ariana Grande COLL was defined as corners +OLL when I checked the wiki for making this video. a few hours after uploading the video, someone changed it to corners of the last layer on the wiki.
J Perm Oh previously when I was learning coll it was corners of last layer(used algs from www.cyotheking.com/coll/)
