Hey trying to understand group theory a bit more. Need some help understanding how to spot which groups are isomorphic to what.(adsbygoogle = window.adsbygoogle || []).push({});

First of all, but silly, but confirmation on what the groups D is dihedral right? What sort of other groups with i have to deal with. Like Z for integers? and U for non-zero integers?

I know it has something to do with cyclic and abelian but i am still unsure.

One of the questions i have is given 4 grroups.

Z100, Z2 x Z50, D50, Z4 x Z25

which of the groups are isomorphic.

Any help is much appreciated.

Thanks
