2x2 EG1 H 4 algorithm
2x2 EG1 H 4 algorithm: 13 turns, opening with U' R U. 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 H 4 belongs to the H group in EG 1.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Reading each side’s upper corner stickers left to right when facing that side gives F: F B; R: U U; B: L L; L: U U. The letters identify colors by their reference faces.

The opening is U' R U; the final segment is U R' U'. This version contains 13 face, wide, or slice turns and no whole-puzzle rotations.
