EO

First step of the four-look last layer: orient the five top edges. 3 cases.

3 cases · 490 algorithms

Proven optimum for 2 cases out of 3; for the others, the page gives the shortest known length and a bound.

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.
