Double commutators?

[benskoning]

what would happen if i did a2 b2 a'2 b'2 also what does this mean for new methods based on commutators.

It would mean nothing. a2 b2 a'2 b'2 ~= a b a' b'

Can you explain what you mean by a2 b2 a'2 b'2?

Double comms, to my knowledge, refer to 2 commutators that cancel together. For example, for 4x4, [l', R U R' U'] [R U R' U', r] which cancels to l' R U R' U' l r U R U' R' r, which you would use to solve the 2 wing pieces for the UB edge (K4LL).

A B A' C B' C' = [A,B] [B,C] = [A:B] [C:B'] = [C: [C' A, B]]

lets say a = R U R' U' so a2 would be R U R' U' R U R' U'
