2x2 EG2 S 2 algorithm
2x2 EG2 S 2 algorithm: 9 turns, opening with R U R'. Case recognition, the complete sequence, and practical execution notes.
Solve the remaining 2x2 corners when the completed first face has a diagonal swap in its layer.
EG2 S 2 belongs to the S group in EG 2.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: B U; R: F U; B: L U; L: B R. The letters identify colors by their reference faces.
Execute the algorithm
R U R' U R U2 R B2 R2
The opening is R U R'; the final segment is R B2 R2. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
