Rubic's cube 4x4x4

I have only two sides that are not right but the other two are right... everything but that has done. How do I complete this 4x4x4 Rubik's cube?

  • $\begingroup$ If you're saying everything is right apart from those two corner cubelets, I don't believe you. The near-top-right one has to go in the green/white/red corner, and the near-top-left corner (the other one that we can see is wrong) is green/yellow/something. I expect red is opposite orange and white is opposite yellow, and the near-bottom-left corner is also wrong. So you need a move to cycle three corners, not two. $\endgroup$

  • $\begingroup$ I bet you can adapt a three-corner cycle from the 3x3x3 cube to do the equivalent job on the 4x4x4. $\endgroup$

  • $\begingroup$ @BeastlyGerbil It looks like a standard cube, so white should be opposite yellow, blue opposite green and red opposite orange. $\endgroup$

I replicated your case on my 4x4x4: enter image description here

This is an adjacent corner PLL parity case which can happen on even-layered cubes (like this 4x4x4, 6x6x6, 8x8x8, etc.)
Put green at the top and the two incorrect corners at the top-front (as in the picture above), and use the following algorithm (Here is an animation for this algorithm):

(Uu)2 (Ll)2 U2 l2 U2 (Ll)2 (Uu)2 F' U' F U F R' F2 U F U F' U' F R

where a capital letter is the outer later, and a lowercase letter is the inner layer (i.e. Uu is the top two layers; l is the inner left slide; etc.)

Source including all 4x4x4 parity cases.

Why do parities happen on a 4x4x4 which aren't possible on a 3x3x3? I (Quuador) and some others explain that here in a recent question on the Cubers-reddit:
What exactly causes 4x4 parities?
