%N Indices k such that A292547(k) = 0.
%C Complement of A290276.
%C Conjecture: for k > 212594 there are no more terms in this sequence (tested for k < 63000000).

%e 3 is in the sequence because A292547(3) = 0
%e 8 is not in the sequence because A292547(8) = -1
%e 201254 is in the sequence because A292547(201254) = 0
%e 212594 is in the sequence because A292547(212594) = 0
