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. Adding in level 10 will take a bit longer. Also, there is some minor new programming involved in this particular effort. When I do get level 10 added in, and do get a match, that should be a complete validation of the new programming, and complete confirmation that the 20-turn sequence is minimal. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Robert G.
