Numbers k such that 2^k == 2 (mod k) and k is divisible by 1093^2. - Jianing Song, Apr 07 2019
Unless there are other Wieferich primes (A001220) besides 1093 and 3511, the intersection and the union of this sequence with A247831 are given by A219346 and A158358, respectively. - Max Alekseyev, Nov 26 2017
