3x3 COLL AS 1 algorithm
3x3 COLL AS 1 algorithm: 7 turns, opening with R' U' R. 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.
AS 1 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 F; B: U F; L: R B. The letters identify colors by their reference faces.
Execute the algorithm
R' U' R U' R' U2 R
The opening is R' U' R; the final segment is R' U2 R. This version contains 7 face, wide, or slice turns and no whole-puzzle rotations.
