1. This is great but Hamming codes are definitely not cryptographic!
They are error-correcting codes (redundant information allowing
for example your CD player to play music, even though your CD has
scratches/errors),
not ciphers (the encryption used so that, for example,you cannot easily
hijack someone's electronic credit card transaction).
2. Here's another plot you might find amusing:
sage: rubik = CubeGroup()
sage: P =
rubik.plot3d_cube("U^2*F*U^2*L*R^(-1)*F^2*U*F^3*B^3*R*L*U^2*R*D^3*U*L^3*R*D*R^3*L^3*D^2")
sage: show(P)
It's the "superflip+4 spot" (in 26q moves, known to be a minimal manuever).
Some conjecture this to be the "longest" move in the quarter-turn metric.
