WebThat is a subset of your group (and even more so a subgroup, albeit unrelated here). And if the group generated is the size of your desired group (you should know the size of A 3 ), then you have all the elements within your group. If you are unfamiliar with cyclic notation please reference the Wikipedia article. Share Cite Follow Webthe order of g is pk, and the order of gpk−1 is p. 3. Let p and q be prime and q ≡ 1 mod p. If G = pnq, then G is solvable. Solution. By the second Sylow theorem there is only one Sylow p-subgroup. Denote it by P. Then P is normal since gPg−1 = P for any g ∈ G. As we proved in class P is solvable, the quotient G/P is solvable.
