%N A058362 Initial primes of sets of 6 consecutive primes in arithmetic progression.
%C A058362 For all the terms listed so far, the common difference is equal to 30. These are the smallest such sets.
%C A058362 It is conjectured that there exist arbitrarily long sequences of consecutive primes in arithmetic progression. As of December 2000 the record is 10 primes.
%C A058362 All terms are congruent to 9 (mod 14). - _Zak Seidov_, May 03 2017
%C A058362 The first CPAP-6 with common difference 60 starts at 293826343073 ~ 3*10^11, cf. A210727. [With a slope of a(n)/n ~ 5*10^8 this would correspond to n ~ 600.] This sequence consists of first members of pairs of consecutive primes in A059044. Conversely, a pair of consecutive primes in this sequence starts a CPAP-7. This must have a common difference >= 210. As of today, the smallest known CPAP-7 starts at 382003672700092872707633 ~ 3.8*10^23, cf. Andersen link. - _M. F. Hasler_, Oct 27 2018
%C A058362 The common difference of 60 first occurs at a larger-than-expected prime. The first CPAP-6 with common difference 90 starts at 8560443932347. The first CPAP-6 with common difference 120 starts at 1925601119017087. - _Jerry M Lagrou_, Jan 01 2024
