I encountered a number theory problem when doing my research:

 1.I want to know whether or not there are infinitely many primes $p$ satistying $gcd(\frac{p-1}{6},6)=1$, such that $6$ is a cubic residue mod $p$, but $2$ and $3$ are not cubic residues mod $p$? If there are, can we give a expression of $p$?

 2. I have deduced that if $p=1296k^2+36k+7$ is a prime, then $p$ satisfies the above conditions. Are there infinitely many such primes?
