The Ab perm

Three corners move round anticlockwise while the front left corner stays home. 11 moves put every piece home.

The last layer is all yellow on top, and every piece of the first two layers is home. What remains is position: three corners move round anticlockwise while the front left corner stays home. This is the Ab permutation, one of the twenty-one ways an oriented last layer can still be shuffled.

Turn the cube in your fingers and look for headlights, a matching pair split by an odd sticker, face the right.

On average one solve in eighteen ends here. The algorithm runs 11 moves; play it slowly first, then step through it turn by turn with your own cube in hand.

Checked by simulation before publishing: the position shown plus the moves shown must produce a finished cube, and the algorithm must touch nothing outside its own job. The diagram and the player are drawn from the same simulated position, so they cannot disagree.
