Abstract: In this talk I will be talking about permutation puzzles. These refer to puzzles in which every valid move performs a permutation of these numbers and can be undone. One clear example of this is the 15-puzzle. One less obvious example (at first) is the Rubik's cube. I will be giving solvability criteria, counting the number of configurations, and calculating the probability of being able to solve from a random starting point.
