WebF(σ)(n) = (σ(n) if n ∈ domσ ∗ otherwise Then F is injective as if F(σ) = F(τ) we see that dom(σ) = F(σ)−1[[A]] = F(τ)−1[[A]]dom(τ) and that we have σ = F(σ) dom(σ) = F(τ) dom(σ) = F(τ) dom(τ) = τ. Composing F with G, we see that Sq(A) ωA. 6 (page 165, # 32) Let FA be the collection of all finite subsets of A. Show that

Web55. Show that a permutation with odd order must be an even permutation. Solution: Let ˙be such a permutation, so in particular ˙r = e, with rodd. As usual, if we write ˙as a product of k2-cycles. Then ˙r will be a product of kr2-cycles. But eis an even permutation (for example, e= (12)(12)) so krmust be even by the well- http://www.maths.qmul.ac.uk/~gnedin/StochCalcDocs/StochCalcSection6.pdf
