Actually, Don wrote a computer solver that works for Rubik’s Cubes in any
dimension…that is, until your computer’s resources run out :)

You were right about it not using the gui interface. Don’s file format for
specifying the state is text based, and Andrey’s recent fractal-like MC7D
design actually reminded me of it a little (since they both rely
on recursion in a manner reminiscent of each other).
Don’s initial post about this is
A post describing typical results (~1700 moves for the 3^4 and ~10K moves
for the 3^5) is here<>
