Let N, denote a set of n distinct symbols that, for convenience, we represent as {1, 2, ..., n}. A permutation of n distinct symbols is a one-to-one mapping from N, to N. Define S, to be the set of all permutations of n distinct symbols. Each element of S, is represented by a permutation of the integers r in 1, 2, ..., n. It is easy to demonstrate that S, is a group:
