Give an alternative proof of Cayley's Theorem by replacing X, (lambda for "left" multiplication) by po (rho for "right" multiplication) defined as follows: pa(x) = xa-r for each ,r E G. Why is xa - ' used here, rather than xa?

Assume that G is a group, and that X, : G * G and pa: G > G are defined by a.a (x) = ax and p,(x) = xa-1 for each x E G. For each a E G, define y, : G * G by y = pa o X,. Prove that each y, is anisomorphism of G onto G. [In the language of Problem 19.27, each y, is an automorphism of G. Notice that, in pa rticular, each y, E Sym(G).]
