Later, I’ll sketch a little bit of the first answer to this challenge, which was given by Pierre de Fermat in an obscure letter to Gassendi, arou…

…was able to reduce the upper bound to 25 moves. He now says he’s already reduced that number to 23, and is currently working on 22. Clearly this will all be over soon. In the worst case, Rokicki will have to keep going until he shows that every cube position can be solved in 21 moves — then this would be the maximum, and the problem would be solved. Solving a Rubik’s Cube. There are roughly 40 quintillion possible positions on a Rubik’s cube — th…
