The set of all permutations of n elements is denoted by Sn and is typically referred to as the symmetric group of degree n. (In particular, the set Sn forms a group under function composition as discussed in Section 8.1.2). WebA permutation is an arrangement of objects in a definite order. The members or elements of sets are arranged here in a sequence or linear order. For example, the permutation of set A= {1,6} is 2, such as {1,6}, {6,1}.
