3x3 OLLCP50 4 algorithm
3x3 OLLCP50 4 algorithm: 10 turns, opening with R B' R. 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: none. Upper edges with that color facing up: UF, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: L U; R: R L; B: U R; L: U U. The letters identify colors by their reference faces.
Execute the algorithm
R B' R B R2 U2 F R' F' R
The opening is R B' R; the final segment is R' F' R. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
