 OFFSET 1,1 LINKS Tomáš Brada, Table of n, a(n) for n = 1..10000 (first 167 terms from Dmitry Petukhov) EXAMPLE Starting from 1107819732769 = A151799(A151799(1107819732821)), the gaps between the next primes are (40, 12, 2, 88, 2, 4, 2, 28, 2, 10, 2, 16, 2, 58, 2, 22, 2, 24, 16) with 8 occurrences of 2, so 1107819732821 is a term. - Michel Marcus, Oct 16 2015 CROSSREFS Cf.
