2x2 EG2 H 4 algorithm
2x2 EG2 H 4 algorithm: 9 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 H 4 belongs to the H group in EG 2.
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: B F; R: U U; B: R R; L: U U. The letters identify colors by their reference faces.
Execute the algorithm
y' R U2 B2 R' U R U' B R'
The opening is y' R U2; the final segment is U' B R'. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
