 OFFSET 1,1 COMMENTS Prime decuplets (p+0,2,6,12,14,20,24,26,30,32) are one of the two types of densest permissible constellations of 10 primes. Maximal gaps between decuplets of this type are listed in A202361; see more comments there. LINKS Dana Jacobsen, Table of n, a(n) for n = 1..27 T. Forbes, Prime k-tuplets G. H. Hardy and J. E. Littlewood, Some Problems of 'Partitio Numerorum.' III. On the Expression of a Number as a Sum of Primes, Acta Math. 44, 1-70, 1923. Alexei Kourbatov, Maximal gaps between prime k-tuples Eric W. Weisstein, k-Tuple Conjecture EXAMPLE The gap of 12102794130 between the very first decuplets starting at p=9853497737 and p=21956291867 means that the initial term is a(1)=9853497737. The next gap after the decuplet starting at p=21956291867 is smaller, so it does not contribute to this sequence. The next gap of 141702673770 between the decuplets at p=22741837817 and p=164444511587 is a new record; therefore the next term is a(2)=22741837817.
