Hey trying to understand group theory a bit more. Need some help understanding how to spot which groups are isomorphic to what.
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
