Bob has already done this in the Notes, except using 7 instead of the trailing 0.
I saw that already, and what I proposed is an alternative to that. Also, he used 7 for the inner cube and 0 for the outer cube, which is contrary to what I proposed.
I don't immediately see whether one is better for a given purpose.
Using 10, 20, etc. is more symmetrical with 01, 02, etc. So, if symmetry is the goal, it seems to be the better alternative.
