3x3 · EO 4a
3x3 EO 4a 2 Top Adj 2 Bot algorithm
3x3 EO 4a 2 Top Adj 2 Bot algorithm: 5 turns, opening with M2 U' M'. Case recognition, the complete sequence, and practical execution notes.
Orient the remaining edges in the Roux last-six-edges stage after solving the blocks and corners.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL, UBL, UBR. Upper edges with that color facing up: UF.
Execute the algorithm
M2 U' M' U' M'
The opening is M2 U' M'; the final segment is M' U' M'. This version contains 5 face, wide, or slice turns and no whole-puzzle rotations.
