The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

 Hints (Greetings from The On-Line Encyclopedia of Integer Sequences!)
 A092647 Absolute value of difference between counts of uninterrupted runs of 4 primes in A092645 and A092646. 2

%I

%S 0,0,1,5,13,34,207,349,631,1257,2295

%N Absolute value of difference between counts of uninterrupted runs of 4 primes in A092645 and A092646.

%C Take the absolute value of the difference between counts of runs of 4 primes congruent to 1 mod 4 and 3 mod 4.

%F a(n) = abs(A092646(n) - A092645(n)). - _Michel Marcus_, Jun 03 2014

%e a(4)=5 because in A092645 the count is 10 and in A092646 the count is 15. 15 - 10 = 5.

%Y Cf. A092645, A092646.
