Consider a puzzle consisting of fifteen numbered squares pla move consists of sliding a numbered square into the adjacent unoccupied square. 13 9 10 11 12 13 1514 13 1415 If we treat the unoccupied square as numbered 16, every configuration corresponds to a permutation in S16. For example, the initial configuration on the left corresponds to the identity, while the configuration in the middle corresponds to the...
