Thank you very much Christopher, those were exactly the algorithms I was looking for, they work great.
The 4x4 axis cube has no constraints at all, it is basically just a shape mod of a 4x4 with oriented centerpieces, so Half turns (other than U2) are allowed, as well as other turns such as D and L.
Hello everyone, this is my first post here.
I have encountered the following situation in the image while solving a 4x4 axis cube, but let's just treat it as a super cube.
I would like to ask whether anyone knows of an algorithm that swaps two diagonally opposite cubies on the last center of a...
