%N Primes p such that p + 512 is also prime.
%C All terms are == 5 (mod 6).
%e 59 and 59 + 512 = 571 are both prime.
%Y Cf. A000040.
%Y Cf. sequences of the type p + k are primes: A001359 (k = 2), A023200 (k = 4), A023202 (k = 8), A049488 (k = 16), A049489 (k = 32), A049490 (k = 64), A049491 (k = 128), A361483 (k = 256), this sequence (k = 512), A361485 (k = 1024).
