WebSolution. The group U12 has four elements: 1,5,7,11. By direct computation the square of each element is 1. But a cyclic group of order 4 must have an element of order 4. Hence the group is not cyclic. 2. a) Show that the group Z12 is not isomorphic to the group Z2 ×Z6. b) Show that the group Z12 is isomorphic to the group Z3 ×Z4. Solution. WebAdvanced Math questions and answers. (3) Let G be a cyclic group and let ϕ:G→G′ be a group homomorphism. (a) Prove: If x is a generator of G, then knowing the image of x under ϕ is sufficient to define all of ϕ. (i.e. once we know where ϕ maps x, we know where ϕ maps every g∈G.)

Let G have order 4. Any element of G has order 1, 2, or 4. If G has an element of order 4 then G is cyclic, so G ˘=Z=(4) since cyclic groups of the same order are isomorphic.

For a finite cyclic group G of order n we have G = {e, g, g2, ... , gn−1}, where e is the identity element and gi = gj whenever i ≡ j ( mod n ); in particular gn = g0 = e, and g−1 = gn−1.
