%N Least prime p such that p-6^n, ..., p-6, p, p+6, ... and p+6^n are primes.
%C This pattern is impossible for n >= 5. See A141281.
%F a(1) = A006489(1), a(2) = A141279(1), a(3) = A141280(1), a(4) = A141281(1).
%e a(4) = 11459317 as this is the least prime p such that p-6^4, p-6^3, p-6^2, p-6, p, p+6, p+6^2, p+6^3 and p+6^4 are all prime. The nine primes are 11458021, 11459101, 11459281, 11459311, 11459317, 11459323, 11459353, 11459533 and 11460613.
