The PLLs that only move the top edges, the corners staying in place. 15 cases.

15 cases · 315 algorithms

No proven optimum for this set: the page gives the shortest known length and a lower bound.

Definition of the set: Lars Vandenbergh's archive.

How to read this page
  • Each case is seen from above: the top face in the middle, the top layer's stickers on its sides, the front face at the bottom.
  • Colours of the puzzle in the application. Grey marks what the case does not look at.
  • Lengths: each move counts 1, an inner slice 2, a rotation 0. The "setup" presents the puzzle as drawn and does not count.
  • In each case, the best optimal algorithm comes first, then the others from the easiest to the hardest to execute (ease score, lower is easier).
  • "Play" starts from the case (the inverse of the algorithm applied to the solved cube) and runs the algorithm on the 3D cube.
