Weba product of two permutations, each of which has order 2. (Experiment ﬁrst with cyclic permutations). Proof. Note that a product of disjoint transpositions has order 2. Let’s do an example ﬁrst. Take a cyclic permutation (a1a2a3a4a5a6). This sends a1 to a2 and so on in a circle. Figure 1. First do (a1 a6)(a2 a5)(a3 a4) and then do (a2 a6 ... WebThe size of a conjugacy class is the number of cycles of the given cycle type. Choose a cycle type, and order the cycles in some order. Consider the n! possible assignments of the integers from 1 to n into the ”‘holes”’ in the cycles. Call two such arrangements equivalent if they define the same permutation. It is clear that this is an equivalence relation, and that …

WebThe general philosophy is that humans like permutations groups. To understand subgroups of a group, you want to think of them as the permutations of something. For subgroups H,K ⊂ G, making the identiﬁcation H = N G(K), really says that under the action of H on G via conjugation (i.e. inner automorphisms), H permutes the elements of K.
