2x2 EG2 T 4 algorithm
2x2 EG2 T 4 algorithm: 10 turns, opening with R2 F2 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 T 4 belongs to the T group in EG 2.
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: L L; R: F U; B: F B; L: U B. The letters identify colors by their reference faces.

The opening is R2 F2 R; the final segment is R U R. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
