L2C

Four centres are done and the fifth already has a two-column block; one algorithm finishes the last two centres. 18 cases.

18 cases · 56 algorithms

Proven optimum for 3 cases out of 18; for the others, the page gives the shortest known length and a bound.

How to read this page

Each case is seen at three quarters: top, front and right faces, plus the top layer's back and left stickers as flat strips.
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.
