3x3 ZBLL L 43 algorithm
3x3 ZBLL L 43 algorithm: 17 turns, opening with y2 F R. Case recognition, the complete sequence, and practical execution notes.
Solve the entire last layer in one sequence when its edges are already oriented.
ZBLL L 43 belongs to the L4 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: L F R; R: U L R; B: B B U; L: L R B. The letters identify colors by their reference faces.

The opening is y2 F R; the final segment is R' U R. This version contains 17 face, wide, or slice turns and 1 whole-puzzle rotation.
