comment About primes and Euler's totient function.
If I have read this correctly then if you change less than to less than or equal to then it will be trivially true? Any prime, $p$, less than n had $gcd(p,n)=1$ and so if we denote the set of integers than are less than $n$ as and reletively prime to $n$ then any prime p less than $n$ will be in $X$ and we are done.

comment If a group G is isomorphic to H, prove that Aut(G) is isomorphic to Aut(H)
This question isn't really that clear. Are you attempting to suppose that $H$ and $G$ are isomorphic and then show that $Aut(G)$ and $Aut(H)$ are isomorphic?

comment Finding the Dual of a primal LP
@calculus No dimensions given but I don't see why that would be relevant? Also is what I have done not correct, I think I have it?
