Apr 28, 2016 at 17:07 | comment | added | Yusuf Gurtas | Thanks for the link maths.lancs.ac.uk/~jameson/cyp.pdf . Theorem 2.5 there answers my question, hence the question asked by @Alex. In fact not only one but all divisors of $\Phi_n(2)$ greater than $n$ are of the form $kn+1$ according to that theorem. It also characterizes the divisors less than $n$. Actually my question is $a=2$ case of that theorem. | |
