WebMar 5, 2024 · We will usually denote permutations by Greek letters such as π (pi), σ (sigma), and τ (tau). 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 any set or subset of objects or events where internal order is significant. Permutations are different from combinations, for which the internal order is not …
