COMMENTS

That is, numbers x = k^5 (mod 3331) for some k. Only 667 numbers occur in this sequence. For the nonresidues, see A184987.

Lehmer states a theorem that says that 3331 is the largest prime for which there are not three consecutive nonzero residues. The other primes having this property are in sequence A188384. - T. D. Noe, Mar 29 2011
