# How to swap two opposite corner pieces of a solved face?

I have a solved white face but I want to swap two opposite corner pieces of the white face to form a T-shape on the back face. How can I achieve this without messing up the other pieces on those two faces?

• To swap the two front corners of the "solved" top white face, do LD'FDDF'DL'. – Anon Aug 7 '16 at 18:13
• Which pieces form this T shape? Or do you not want to change any cubie on the back face? Do you just mean you have the other two of the first layer in their correct positions? – Jonathan Allan Aug 7 '16 at 19:03

As far as I can tell from the question so far it would appear that you mean you have solved the white face (U) and have all of the first layer - the ring around that face is all of the correct colour - except for to opposite corner cubies like so, or a mirror image (or colour change):
R2 F' R2 D2 R2 F R2 - Singmaster notation
The first three moves will set the two corners onto opposite locations in the bottom layer with everything else out of the way; the D2 swaps them; and the last three put everything back again.
