3x3 ZBLL U 47 algorithm
3x3 ZBLL U 47 algorithm: 15 turns, opening with R' U2 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 U 47 belongs to the U4 group in ZBLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. 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 R B; R: L L R; B: U B U; L: R F L. The letters identify colors by their reference faces.

The opening is R' U2 R; the final segment is R U R. This version contains 15 face, wide, or slice turns and no whole-puzzle rotations.
