If (1) denotes the identity permutation, then P(1) is the identity matrix. Let Sn denote the symmetric group, or group of permutations, on {1,2,...,n}. Since there are n! permutations, there are n! permutation matrices. By the formulas above, the n × n permutation matrices form a group under matrix multiplication with the identity matrix as the identity element. The map Sn → GL(n, Z2) that sends a permutation to its column representation is a faithful repre… WebSymmetric Group • S n = permutations of n things • Contains n! elements • S 3 =permutations of {1,2,3} (123, 132, 213, 231, 312, 321) • Permutations can be represented with n × n matrices • Character: trace of a matrix representation • Character Table: table of all irreducible characters of a group
