3x3 COLL Pi 5 algorithm
3x3 COLL Pi 5 algorithm: 11 turns, opening with R U' L'. Case recognition, the complete sequence, and practical execution notes.
Solve the last-layer corners with the last-layer edges already oriented; edge permutation may remain.
Pi 5 belongs to the Pi group in COLL.
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, UL, UB, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: B U; R: F B; B: U F; L: U U. The letters identify colors by their reference faces.

R U' L' U R' U L U L' U L
The opening is R U' L'; the final segment is L' U L. This version contains 11 face, wide, or slice turns and no whole-puzzle rotations.
