%N Initial primes in prime triples (p, p+2, p+6) preceding the maximal gaps in A201598.

%C Prime triples (p, p+2, p+6) are one of the two types of densest permissible constellations of 3 primes. Maximal gaps between triples of this type are listed in A201598; see more comments there.

%e The gap of 6 between triples starting at p=5 and p=11 is the very first gap, so a(1)=5. The gap of 6 between triples starting at p=11 and p=17 is not a record, so it does not contribute to the sequence. The gap of 24 between triples starting at p=17 and p=41 is a maximal gap - larger than any preceding gap; therefore a(2)=17.
