WebWe want to classify groups of order 60 up to isomorphism. I will assume that you are familiar with the classi cations of groups of orders 12, 15, and 20. Let Gbe a group of order 60. Let P be a Sylow 5-subgroup, Qbe a Sylow 3-subgroup, and Rbe a Sylow 2-subgroup of G. We know that P˘=Z 5, Q˘=Z 3, and R˘=Z 4 or Z 2 Z 2. A direct application ... Small groups of prime power order p are given as follows: • Order p: The only group is cyclic. • Order p : There are just two groups, both abelian. • Order p : There are three abelian groups, and two non-abelian groups. One of the non-abelian groups is the semidirect product of a normal cyclic subgroup of order p by a cyclic group of order p. The other is the quaternion group for p = 2 and a group of exponent p for p > 2. milford cdjr auto clearance

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 ... Web121.
