1. The problem statement, all variables and given/known data Let G be a group with identity e and product ab for any elements a and b of G. Let ф: G⟶G be a map such that Ф(a sub1)ф (a sub2)ф(a sub3) = ф(b sub1) ф(b sub2) ф(b sub3) whenever, (a1) (a2)(a3) = e=(b1) (b2) (b3) for any(not necessarily distinct) elements a1 ,a2 ,a3, b1, b2, b3 of G. Prove: There exists an element a in G such that the map @: G⟶G defined by @(x) = a ф(x) for every element x in G, is a homomorphism. 2. Relevant equations Def: A homommorphism Ф from a group G to a group G is a mapping from G to G that preserves the group opperation. That is, Ф(ab) = Ф(a)Ф(b) for all a, b in G Properties of elements under a homomorphism: Ф carries the identity in G to the identity in G Ф preserves inverses *note that the Ф in this section is not the same as in the question... 3. The attempt at a solution I really havent got a clue on where to even begin to define "a" I am thinking that it needs to be triplet for example aea^(-1)...but I have no idea what to do or where to start....I am completely lost, can anyone give me a push in the right direction?
