 OFFSET 1,1 COMMENTS a(n) is the smaller of the two consecutive primes having a late occurring prime gap g = p_k+1 - p_k. All even gaps smaller than g occur at a smaller prime. Also, the next even gap g+2 also occurs earlier. REFERENCES P. Ribenboim, The Little Book of Big Primes. Springer-Verlag, 1991, p. 144. LINKS T. R. Nicely, List of "First occurrence prime gaps" Eric Weisstein's World of Mathematics, Prime Gaps EXAMPLE 1831 is in this list because the next prime is 1847, giving a prime gap of 16. All even gaps less than 16 occur before this (for smaller primes) and the next even gap, 18, also occurs earlier. CROSSREFS Cf. A000230, A001223, A001632, A038664, A086978, A086979, A086980, A002386.
