%N Numbers n such that antisigma(n) = antisigma(n+1) + 12; where antisigma(n) = A024816(n).
%C Supersequence of A227756 (primes p such that sigma(p+1) = 2*p+14).
%C The composites in this sequence are rare: 1359, 453967, ... (no more up to 10^6).

%e 1359 is in sequence because antisigma(1359) = 922144 = antisigma(1360) + 12 = 922132 + 12.
