%N Primes occurring in exactly three prime triples (p,q,r) with p<q<r=p+6.
%C A098418(a(n)) = 3; subsequence of A098420.
%C This sequence consists of all integers of the form (prime(m)*prime(m+4)+36)/prime(m+2), for m>0, where prime(m) = A000040(m). Also note that the integers resulting from that rule equal prime(m+2), therefore a(n) also consists of all integers of the form sqrt[prime(m)*prime(m+4)+36]. - _Richard R. Forberg_, Jan 11 2016

%e A000040(27)=103: A007529(11)=103, A098414(10)=103 and A098415(9)=103, therefore 103 is a term.
%Y Cf. A098419, A098421, A098422.
