A233435 Primes p in prime triplets (p, p+4, p+6) at the end of the maximal gaps in A201596. 2

Prime triplets (p, p+4, p+6) are one of the two types of densest permissible constellations of 3 primes. Maximal gaps between triplets of this type are listed in A201596; see more comments there.

The gap of 6 between triplets starting at p=7 and p=13 is the very first gap, so a(1)=13. The gap of 24 between triplets starting at p=13 and p=37 is a maximal (record) gap - larger than any preceding gap; therefore a(2)=37. The gap of 30 between triplets at p=37 and p=67 is again a record, so a(3)=67. The next gap is smaller, so a new term is not added to the sequence.
