COMMENT

Primes p such that x^3 = 2 has more than one solution mod p.

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)

Subsequence of A040028, complement of A059437 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), Mar 02 2001
