WebProblem 7.6. Prove that Qpos is not isomorphic to Z. Proof. Suppose for contradiction that Qpos is isomorphic to Z where Qpos is a group under multiplication and Z is a group under addition. That means there exists an isomorphism f : Qpos → Z. Since f is an isomorphism, f is onto. That means for every y ∈ Z there is an x ∈ Qpos s.t. f(x) = y.

The only elements of order 4 are the 4-cycles, so each 4-cycle generates a subgroup isomorphic to ℤ / 4 ⁢ ℤ, which also contains the inverse of the 4-cycle.

Weba) 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. a) The element 1 ∈ Z12 has order 12. Every element (a,b) ∈ Z2 × Z6 satisfies the equation 6(a,b) = (0,0). Hence the order of any element in Z2 × Z6 is at most 6, and the groups can not be isomorphic.
