(The “conjugation rewrite lemma”.) Let σ and τ be permutations. (a) Show that if σ maps x to y then στ maps τ(x) to τ(y). (b) Suppose that σ is a product of disjoint cycles. Show that στ has the same cycle structure as σ; indeed, wherever (... x y ...) occurs in σ, (... τ(x) τ(y) ...) occurs in στ.
