%N Numbers n for which A242720(n) = prime(n)*(prime(n)+8)+3.
%C prime(n)*(prime(n)+8) + 3, such that prime(n)+8 and prime(n)*(prime(n)+8)+2 are primes, is the third minimal possible value of A242720(n) after (prime(n)+1)^2 + 2, n>=3 (cf. A246824) and prime(n)*(prime(n)+4) + 3 (cf. A247280).
%F If n is in the sequence, then prime(n) == 1 (mod 10), A242720(n) == 12 (mod 100).
%Y Cf. A242719, A242720, A242847, A245363, A246748, A246824, A247011, A147280.
