If σ is a k-cycle with k odd, prove that there is a cycle τ such that τ^2=σ.
I know that every cycle in Sn is the product of disjoint cycles as well as the product of transpositions; however, I'm not sure if using these facts would help me with this proof. Could anyone point me in the right direction?
