## Swap UF Corners

The formula R U2 R' U' R U2 L' U R' U' L' is wrong. Can anybody correct it? It's probably a typo, but I can't reconstruct it. Cuc (talk) 18:14, 23 December 2016 (UTC)

- The algorithm is correct but it swaps the UR corners, not the UF corners. I've added a
*y'*rotation to show this. EastsheenFan (talk) 13:34, 24 December 2016 (UTC)- I performed it on a regular cube and I noticed that the last L' should be replaced by an L. I am sorry that I did not see this on a 2x2 at once. Please, verify. And yes, the y' helps too :-) Cuc (talk) 05:57, 26 December 2016 (UTC)
- Oh yes, you're right; that should indeed be an L. I didn't notice that! EastsheenFan (talk) 16:01, 29 December 2016 (UTC)
