4. (a) Suppose that τσ=(1 5 2 3)(4) and στ=(1 2 4 5)(3) in S5. If σ1 = 2, find σ and τ. (b) In Sn, show that σ = τ if and only if σ(τ)^(−1) = ε. ε is the identity permutation. Must be written as a proof. (c) Let σ=(1 2 3) and τ=(1 2) in S3. Show that S3={ε,σ,σ^2,τ,τσ,τ(σ)^2} and that σ^3=ε=τ^2 and στ=τ(σ)^2, then fill out the multiplication table for S3.
