%N A277018 Numbers n for which A277017(n) = 0; range of A277022 sorted into ascending order.
%C A277018 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).
%C A277018 Indexing starts from zero as a(0) = 0 is a special case in this sequence.
