I have posted a bit on my version of Kociemba's program, and I can only conclude that my program is too fast. After doing the superfliptwist, the superflip and the supertwist I thought about trying those configurations where Singmaster's notes did not give a solution better than 21 moves. I find now that it takes more time to enter the configurations than what the program needs to solve it! Upto now I found the following (I will not give the exact moves, as I think Kociemba wants to publish a bit more about this): superflip: 20 moves supertwist: 16 moves superfliptwist: 20 moves Walker's 6+: 17 moves (was 22) Walker's 6X: 19 moves (was 25) Walker's worm: 14 moves (was 23) Initialization time for the program is 2.5 minutes. But it finds solutions after only a few seconds! If you have a configuration that you think is at a large distance from start, mail it and I will disprove it ;-). dik -- dik t. winter, cwi, kruislaan 413, 1098 sj amsterdam, nederland dik@cwi.nl
