There are 43,252,003,274,489,856,000 different possible configurations of the coloured squares on any Rubik’s Cube.

(But now an international team of enthusiasts in California, using one of Google’s supercomputers, have calculated that you’re never more than 20 moves away from solving this famously annoying puzzle. And, what’s even worse, if like me you’ve never figured it out, is that only 300 million arrangements ā€“ a small fraction of the total number ā€“ require a full 20 moves, the majority of solutions should only take between 15 and 19! I’m going to have to get up in the attic to find mine, and give it another go, after all, I can always just move the stickers.)
