 OFFSET 1,1 COMMENTS The sequence counts the terms in the runs of composites associated with A136798-A136799. A129856 is obtained by removing the composites (9, 15 etc.) from this sequence. This is sequence A046933, with the zero and all the 1's deleted. - R. J. Mathar, Jan 24 2008 LINKS FORMULA a(n)=A136799(n)-A136798(n)+1. EXAMPLE a(1)=3 because in the run 8, 9, 10 there are three terms. MATHEMATICA Select[#[[2]]-#[[1]]-1&/@Partition[Prime[Range[100]], 2, 1], #>2&] (* Harvey P. Dale, Apr 08 2015 *) CROSSREFS Cf.
