3x3 COLL AS 3 algorithm

Solve the last-layer corners with the last-layer edges already oriented; edge permutation may remain.

AS 3 belongs to the Anti Sune group in COLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UBL. 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: U L; R: U B; B: U L; L: F R. The letters identify colors by their reference faces.

The opening is y2 R2 D; the final segment is R U' R'. This version contains 11 face, wide, or slice turns and 1 whole-puzzle rotation.
