2x2 EG2 L 4 algorithm
2x2 EG2 L 4 algorithm: 11 turns, opening with y R U2. 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 L 4 belongs to the L 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, UBR. Reading each side’s upper corner stickers left to right when facing that side gives F: R B; R: U B; B: L U; L: L F. The letters identify colors by their reference faces.

The opening is y R U2; the final segment is R B2 R2. This version contains 11 face, wide, or slice turns and 1 whole-puzzle rotation.
