The correct placement of a corner piece is between center pieces with the same colors. To get the diagonal corner swap you need to do an additional U or U' move. Think of the algorithms as moving a piece out of the way, setting up its correct position, and then moving the piece into that place. But if you ever have a question about anything, feel free to leave a comment on one of my videos! (I tried making a single quarter turn of my cube, but re-solving it with combinators just put it into the same state, of needing two corners to be swapped. As you want and without pauses while you do not have all yellow tiles on yellow. Similar to a Chinese finger trap, the harder you try to solve it the more difficult it gets. If it can't, is there some easy principle through which the parity can be removed? I knew what sledgehammer did beforehand, but what if I did not know how it affected the cube? Swapping two diagonal corners is done by performing the adjacent swap algorithm twice. If your corner piece is in any of these positions then go to Action 2 below. Lastly, rotate the top layer until all of the corners are in the right place. This works because the algorithm only moves two pieces, allowing you to do set up moves to change which two pieces are changed. Is every feature of the universe logically necessary? In which case you can use a combination of R' D' R D (2x) sequences with setup moves to solve this. Why is sending so few tanks Ukraine considered significant? You can simple do [U2, T perm].
