Hi,

I’ve created a new page in the wiki to include the MPUlt records:

http://wiki.superliminal.com/wiki/MPUlt_Records

Please feel free to correct me if I was not the first to solve any puzzles, or, certainly, add your records.

A question: Is there any publicly accessible link to the MPUlt program? I’m referring to [http://games.groups.yahoo.com/group/4D_Cubing/files/Andrey/MPUlt.zip], but it seems like one has to be a member of this group to download it.

What I did was to use one twist to fix this edge, and re-solve the others, which is half the hypercube. In retrospect, I still don’t know how to prevent it in the beginning.
