I love how smooth the cube sounds when you turn slow aswell, i like using my cube as a fidget toy sometimes, kind of like a fidget spinner but doing slow algorithms
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
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

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.
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!
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.
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!
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").

J Perm thanks I was thinking like, the cases you use x cross and coll ,ollcp instead of oll and pll . My best is like 35secs and I would like to get better and not learn unwanted algs
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.
+CHIN KEE HAW orientation. it's obvious for last layer, whether an edge is correctly oriented or not. but every edge has an orientation, and if it's bad then that just means it can't be solved with R/U/L/D moves. in cfop, you rotate because you can't solve a bad edge with R/U/L and by rotating you can change its orientation.
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.
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.

Hey J Perm! What is R U R' U R U2' R' ? That's what you did at 1:57, instead of R U R' U R U2 R'. I can't find anything online referencing that variation, and I'm curious why that came out of your fingers instead of a regular sune (and the notation you posted)
+CSMPiano OLLCP is more worth it for the good cases, since they are more common. I have a video from like last year about the OLLCPs that I use that are easy to learn. But after learning easy ones, I think ZBLL is better after that. 2GLL is definitely worth it for OH, since 2-gen COLLs are basically the same length as a 2GLL for most cases. For 2H it's just as worth it as any other ZBLL.
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.
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
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.
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)

2GLL is definitely worth it for OH, since 2-gen COLLs are basically the same length as a 2GLL for most cases. For 2H it's just as worth it as any other ZBLL.
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 :)
@J Perm how do you figure out whether to insert the pair a normal way or use sledgehammer
is it better to memorize coll and ollcp, or just regular oll and pll?
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 if OLLCP can be applied to any OLL case (so cross cases as well)... That pretty much means that COLL is included inside OLLCP right? Or not?
BBCuber99
Yes. COLL is a subset of OLLCP.
Me: Does TeamBLD
Partner: Okay, do a Soonay
Me: ????
Partner: You have to be kidding
4:25 but removing the best and worst time isn’t either mean median or mode...?
It doesn't have to be one of those 3, they are just common examples
Voided If Broken ok thanks
Is there a name for this one?
Connor Gaughan not specifically. That’s why we just call it average.
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/)
What are the algs that you use for PLL T and L?
1:39 When he's not even trying and he beats your record by almost four seconds.
Thank you for this!
A lot of useful information :D
+Hatulim glad u liked it!
Another wonder video no words for this!!!
I always enjoy your vids, dude.
+Terrence Duenas thanks!
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
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)
Hi, just to let you know your content is super helpful on this channel and i cant wait to see more. Do you know what zbll means ?
thanks! ZBLL is an algorithm set with over 400 algs. it solves last layer as long as you have the top cross done
if you sometimes need to auf in cfop then why isnt it called cfopa?
2:57 For example about 3-gen, J Perm has RUL algorithms: R U2' R' U' R U2' L' U R' U' L
I started a 6x6 as this video started and finished perfectly in time with the end
The only person ever with a good first vid
I would say gen is very popular for stuff like Roux
+TheJor27 oh yeah forgot about that.
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
What alg did he use for the L case ???
