Note the word *long*. There is a 20-turn sequence for superflip.
I think we have a winner. I compared the data base for level 0
through 9 against the same data base superflipped, with no
matches. That should mean that there is no 18-turn or less
sequence for superflip.
wait a moment. dik is talking about face turns. what are you
talking about? face turns or quarter turns?
and if you're talking about face turns, there's no reason an odd
length maneuver can't exist.
