A minor glitch, but the Megaminx scrambling regulations call for 70 moves, but it should actually be 77. 10 moves followed by a U or U' =11 moves... 11 moves x 7 lines = 77 moves

Not really. D++ U is equivalent to D-- y' for example. The scramble is written as 77 moves but is actually only 70.

I hadn't looked at it that way, thanks for pointing that out.
