WebWe will not explain here why every group of order 16 is isomorphic to some group in Table1; for that, see [4]. What we will do, in the next section, is explain why the groups in Table1are nonisomorphic. In the course of this task we will see that some nonisomorphic groups of order 16 can have the same number of elements of each order. 2. Web4 is not isomorphic to D 12. Solution. Note that D 12 has an element of order 12 (rotation by 30 degrees), while S 4 has no element of order 12. Since orders of elements are preserved under isomorphisms, S 4 cannot be isomorphic to D 12. 9.23. Prove or disprove the following assertion. Let G;H;and Kbe groups. If G K˘=H K, then G˘=H.
