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
quarter-turn metric
The unique (within rotational variations) furthest position in the quarter-turn metric is 26 moves from solved, as described at

solutions
- Jim's: edges first, then corners, using
- commutators of adjacent side quarter turns
- "preparation" moves before and after those commutators, and
- commutators of sequences that leave one layer unchanged, as discussed in Oct 7 notes.
