%N a(n) is the smallest odd prime p that has exactly n consecutive distinct prime "prime gaps" between p and a larger prime.
%C Here, prime gap is defined as the number of composites between a prime and the next prime.

%e a(4) = 491 because 491 (followed by 7 composites) 499 (followed by 3 composites) 503 (followed by 5 composites) 509 (followed by 11 composites) 521, and {7, 3, 5, 11} are 4 consecutive distinct prime prime gaps.
