Zn: the cyclic group of order n (the notation Cn is also used; it is isomorphic to the additive group of Z/nZ).Dihn: the dihedral group of order 2n (often the notation Dn or D2n is used )Sn: the symme ...
The list can be used to determine which known group a given finite group G is isomorphic to: first determine the order of G, then look up the candidates for that order in the list below. If you know w ...
