3x3 ZBLL L 3 algorithm

Solve the entire last layer in one sequence when its edges are already oriented.

ZBLL L 3 belongs to the L1 group in ZBLL.

Recognize this starting position

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

The opening is y' R' U2; the final segment is R' D R2. This version contains 11 face, wide, or slice turns and 1 whole-puzzle rotation.
