Hey schuma, welcome to the group! I was hoping to see you here. I
wish there was more overlap between the different twisty puzzle
groups. Your conquest of Gelatinbrain’s puzzles was a real
tour-de-force so I look forward to seeing what you can do with the more
exotic polytopes available in MC4D 4.0.

You solve very quickly with macros, maybe you should think about
practicing the 3^4 a couple more times and then joining the
Hyperspeedcube Challenge on the 18th:

Good luck with your move, Melinda’s in the Bay Area too. As a native
Californian I’m pleased to have one of the best living here. Perhaps I
will have stop telling people that you’re actually just a puzzle solving
AI running in a secret government installation in the basement of a
Boston University lab ;-)

Finally, I think your "Rubik’s Square" program is of some interest to
this group:
