3x3 OLLCP20 1 algorithm
3x3 OLLCP20 1 algorithm: 17 turns, opening with R U 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, UBL, UBR. Upper edges with that color facing up: none. Reading each side’s upper corner stickers left to right when facing that side gives F: R R; R: B L; B: F B; L: L F. The letters identify colors by their reference faces.
Execute the algorithm

The opening is R U R'; the final segment is R U2 R'. This version contains 17 face, wide, or slice turns and no whole-puzzle rotations.
