So an automorphism is a group G to itself.(adsbygoogle = window.adsbygoogle || []).push({});

So how do you prove that in general? Is it the same to proving an isomorphism?

So suppose they ask to find Aut(Z). what do I do?

Z is all the ingegers, from 1 to n.........so how do prove that?

how do i start?
