3x3 ZBLL AS 72 algorithm
3x3 ZBLL AS 72 algorithm: 17 turns, opening with y' R2 D'. Case recognition, the complete sequence, and practical execution notes.
Solve the entire last layer in one sequence when its edges are already oriented.
ZBLL AS 72 belongs to the AS6 group in ZBLL.
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 top row left to right when facing that side gives F: U R B; R: U B L; B: U L L; L: F F R. The letters identify colors by their reference faces.

The opening is y' R2 D'; the final segment is R' F' R. This version contains 17 face, wide, or slice turns and 1 whole-puzzle rotation.
