%N Prime 5-tuple 10000024493 + K * 30 for K = 0 to 4.
%C A052243(20) = 9843019 and A052243(21) = 9843049 are the first two primes in the smallest 5-tuple with difference 30 reported by Lander and Parkin in 1967. The much larger 5-tuple beginning with 10000024493 was reported by Jones, Lal and Blundon in the same year.
%C Sequence A059044 lists the quintuplets of consecutive primes in arithmetic progression (CPAP-5). A059044(9) ~ 10^8, A059044(86) ~ 10^9. a(1) ~ 10^10 might occur in that sequence around index n = 1000. - _M. F. Hasler_, Oct 28 2018
