# $4\times4\times4$ Rubiks cube Top Layer Issue The only way i am able to solve is to jumble the whole cube again. If you know the way to solve pls give images or algorithm.

• If you truly want to understand the cube and other permutation puzzles, you need to learn commutators, as explained in this post. Then it is obvious that this is a double pair swap, which can be easily done using 2 commutators. Of course there are shorter solutions, but they are ad-hoc and require memorization. Nov 3 at 11:35

It's a 4x4 Parity.

The algorithm to solve is,

$$(2R)^2U^2(2R)^2u^2(2R)^2(2U)^2$$

Where $$2R$$ is the second layer from right, $$U$$ is the top layer, $$u$$ is top two layers combined, $$2U$$ means second layer from top and the superscript implies you have to turn twice.

First hold the cube in this position. # STEP 1: $$(2R)^2$$ # STEP 2: $$U^2$$ # STEP 3: $$(2R)^2$$ # STEP 4: $$u^2$$ # STEP 5: $$(2R)^2$$ # STEP 6: $$(2U)^2$$ • Beautiful. can you share link for more of these combos Jun 2 '19 at 15:17
