%N A014752 Primes of the form x^2 + 27y^2.
%C A014752 Primes p such that x^3 = 2 has more than one solution mod p.
%C A014752 Primes p == 1 mod 3 such that p is a cubic residue mod p.
%C A014752 Primes p == 1 mod 6 such that 2 and -2 are both cubes (one implies other) 
               mod p. - Warren Smith (wds(AT)research.nj.nec.com)
%C A014752 Subsequence of A040028, complement of A045309 relative to A040028. Solutions 
               mod p are represented by integers from 0 to p-1. For the terms of 
               this sequence, x^3 = 2 has three solutions mod p, whose sum is p 
               (A059899) or 2*p (A059914). The solutions are given in A060122, A060123 
               and A060124. - Klaus Brockhaus (klaus-brockhaus(AT)t-online.de),
