3x3 ZBLL H 24 algorithm

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

ZBLL H 24 belongs to the H2 group in ZBLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: none. 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: F L L; R: U R U; B: R F F; L: U B U. The letters identify colors by their reference faces.

Execute the algorithm

y' R U R2 F R F' Rw U' Rw' U Rw U Rw'

The opening is y' R U; the final segment is Rw U Rw'. This version contains 13 face, wide, or slice turns and 1 whole-puzzle rotation.
