WebDefinition: A permutation τ of n elements is a bijective function having the set { 1, 2,..., n } both as its domain and codomain. The number of permutations of n elements, and hence the cardinality of the set S n is n! So for example, for every integer i ∈ { 1, 2,..., n } there exists exactly one integer j ∈ { 1, 2,..., n } for which τ ( j) = i.

WebA permutation is an arrangement in a definite order of a number of objects taken some or all at a time. Let us take 10 numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
