information

God's algorithm

Full computer search finished in 2010, using half or quarter twist of a face moves, with face centers stationary.
The cube lover's forum collects and discusses what's known of the theoretical and computational limits.

half-turn metric

Any position can be solved with 20 quarter- or half-turn moves - see http://www.cube20.org/.

quarter-turn metric

The unique (within rotational variations) furthest position in the quarter-turn metric is 26 moves from solved, as described at http://www.cube20.org/qtm/.
