    Just a quick note on “God’s number”: Rokicki/Kociemba/Davidson/Dethridge had already proven Rubik’s cube’s solvability in 20 moves or less (via enumeration) []. Demaine et al. provide a formal proof which holds for generalized n × n × n cubes and show that those can be solved optimally in Θ(n^2 / log n) moves.
