3x3 OLLCP1 4 algorithm

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: none. Reading each side’s upper corner stickers left to right when facing that side gives F: F L; R: U U; B: L B; L: U U. The letters identify colors by their reference faces.

The opening is y R U'; the final segment is R2 U R'. This version contains 11 face, wide, or slice turns and 1 whole-puzzle rotation.
