http://sporadic.stanford.edu/Math121/Solutions7.pdf WebGroups of Order 6 We will classify groups of order 6. We know two such groups already, the cyclic group Z 6, and the symmetric group S 3. These groups cannot be isomorphic to each other since Z 6 is cyclic, hence abelian, and S 3 is not abelian. The basic game plan then is to deduce enough about the group to see that there are at most 2 group ...

WebBy the recognition theorem for semidirect products, G ≅ H ⋊ φ K for some φ: K → A u t ( H).

WebSince P is normal, we can construct the subgroup PR, which has order 20. There are 20 elements with orders not 3 or 15, so at most 20 elements with an order which divides 20, so at most one subgroup of order 20. Hence PR is the unique subgroup of order 20, hence characteristic, and hence normal.
