Clever use of the corner move at minute 24, I don’t think I’ve seen that one before. I certainly never thought of it on my own! When I solve this puzzle, I like to do the top and bottom faces first, so the corners are taken care of. Then I use commutators to solve the second layer. Then if all the unsolved edges are in the third layer and the corners are solved, parity can be dealt with by moving the third layer a quarter turn. That is, there will be two unsolved edges in the third layer. If they are next to each other, turn a quarter turn either direction, and there are three unsolved edges in the third layer. 3 cycle and the edges are done. Then all,that's left is to tidy up the remaining centers. There's an annoying case where the 2 unsolved edges in the third layer are opposite each other, so a quarter turn makes the other two solved. A 3 cycle will make it into the adjacent solved edges case. I think that is all the cases - the edges have to be oriented right to be on that layer with all other edges and corners solved. It can’t be the case that 3 are solved and one unsolved or that all 4 are unsolved. The disadvantage is that then I have to solve the centers in the third layer last. If I solved them before, the parity alg will mess them up again. I’ve been doing this long enough I don’t think I can remember my old parity algorithm.
This puzzle would actually be nice if it was turning well. But LanLan just made it so horrible that I will probably never touch it again. I also made a video on my channel on the Octahedron by the way, but my method is different. I thought that edge pairing is way too confusing here. After seeing your video, though, I might reconsider this. You make it look so easy.
Yes, still have a mortgage to pay. The school I'm at is fairly reasonable to teach at, kids are great, and I'm teaching the classes and year levels I want, which always helps. If I get my mortgage paid off, all bets are off though!

Love my 4x4x4 Octahedron. Try and solve it at least every two weeks so I don't forget how. Thanks for teaching me.

How are you going? Are you still teaching? I've quit - can't stand it anymore.
Love your work.
