2x2 EG1 AS 4 algorithm
2x2 EG1 AS 4 algorithm: 10 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 an adjacent swap in its layer.
EG1 AS 4 belongs to the AS group in EG 1.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UBL. Reading each side’s upper corner stickers left to right when facing that side gives F: U R; R: U B; B: U L; L: F L. The letters identify colors by their reference faces.
Execute the algorithm
R U' R' F' U' R U R' U' F
The opening is R U' R'; the final segment is R' U' F. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
