2x2 EG2 Pi 5 algorithm

Solve the remaining 2x2 corners when the completed first face has a diagonal swap in its layer.

EG2 Pi 5 belongs to the Pi group in EG 2.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Reading each side’s upper corner stickers left to right when facing that side gives F: F U; R: L B; B: U L; L: U U. The letters identify colors by their reference faces.
