3x3 OLLCP28 4 algorithm
3x3 OLLCP28 4 algorithm: 9 turns, opening with R2 F2 Rw. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer and solve its corner permutation together; edge permutation may still remain.
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: UL, UB. Reading each side’s upper corner stickers left to right when facing that side gives F: F R; R: B B; B: L F; L: R L. The letters identify colors by their reference faces.
Execute the algorithm
R2 F2 Rw U Rw' F2 R F' R
The opening is R2 F2 Rw; the final segment is R F' R. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
