COMMENTS

Numbers such that no run of 1-bits has length >= A000040(1 + the total number of 0-bits anywhere right of that run in the binary expansion of n).

Indexing starts from zero as a(0) = 0 is a special case in this sequence.

FORMULA

Other identitities:

A129251(A005940(1+a(n))) = 0 for all n.

EXAMPLE

60 ("111100" in binary, A007088) is present as 4 < prime(2+1) = 5.

PROG

(Scheme, with Antti Karttunen's IntSeq-library)

(define A277018 (ZERO-POS 0 0 A277017))
