Let G=Zp+Zp .How many automorphisms does G have?
Please explain clearly the counting principle.
G=Zp+Zp, so each element in G has the form (a,b),where a,b are in Zp.
G has two generators (1,0) and (0,1) since ...
This shows how to find how many automorphisms a group has. The counting principle is explained.
