2x2 EG1 L 4 algorithm

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

EG1 L 4 belongs to the L group in EG 1.

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: B L; R: U L; B: F U; L: F R. The letters identify colors by their reference faces.

The opening is y R' F; the final segment is R U2 R'. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
