The "official" world record was set by Minh Thai at the 1982 World Championships in Budapest Hungary, with a time of 22.95 seconds. Keep in mind mathematicians provided standardized dislocation patterns for the cubes to be randomized as much as possible. I think the Guiness Book of Records dropped the entry in the 1985 edition due to the fact that the contests all dried up. Interestingly David Allen, the #2 cubist in the United States, also uses the Jeff Varasano method. I met him in Buffalo NY in the a regional American Cube-a-thon on Sept 18, 1982. (Yes, that long ago!) Did you enter any of the tournaments Derek?

I use computer generated sequences for a lot of patterns and I find them quite useable in some cases. Also the < U, R > group processes only use 2 sides, and those I can do without moving the cube in space. Usually I rotate them in space first. -> Mark <- Email: mark.longridge@canrem.com
