3x3 OLLCP19 4 algorithm
3x3 OLLCP19 4 algorithm: 10 turns, opening with y' S' 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: UFR, UFL. Upper edges with that color facing up: none. Reading each side’s upper corner stickers left to right when facing that side gives F: F R; R: B U; B: B R; L: U L. The letters identify colors by their reference faces.

The opening is y' S' R; the final segment is F R F'. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
