2x2 EG1 T 4 algorithm

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

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

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: F F; R: R U; B: R L; L: U L. The letters identify colors by their reference faces.

Execute the algorithm

y' U2 R' F R F' U R U' R' U F R U' R'

The opening is y' U2 R'; the final segment is R U' R'. This version contains 14 face, wide, or slice turns and 1 whole-puzzle rotation.
