(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Let P be a prime integer, prove that Aut(Z sub P) ≈ Z sub p-1

2. Relevant equations

none

3. The attempt at a solution

groups must preserve the operation, be 1-1, and be onto and they can be called an isomorphism. Z sub p-1 has one less element in it so and all the elements in them are the same except for the one less element. Not sure what this tells me though. HELP ME FOR LINEARRRRR
