5. ### There is a unique homomorphism θ : ZZ6 → S3 such that θ([1]) = (1 2 3)?

We can actually write out all of the elements of θ. Since θ is a homomorphism, multiplication by n in Z6 corresponds to nth power in S3. θ([0]) = θ(0 * [1]) = (1 2 3)^0 = (1) θ([1]) = (1 2 3) θ([2]) = θ(2 * [1]) = (1 2 3)^2 = (1 3 2) θ([3]) = θ(3 * [1]) = (1 2 3)^3 = (1) θ...
