On the one hand, that seems astonishingly good to me, being fairly close to the solutions from early Thistlethwaite programs. On the other hand, it is roughly double (depending, I suppose on whether H-turns are counted or not) what is probably the true God's Algorithm. Hence, it doesn't tell us much about God's Algorithm except that the speed cubists are very, very good. On another subject, my Cube Theory 101 article said that the apostrophe was used in E-mail to denote complements, when of course it is used to denote inverses -- not the same thing as complements at all. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Robert G.
