%N Numbers k such that A026600(k) = 3.
%C It appears that a(n) gives the position of its own n-th 1 modulo 3 term, the n-th 2 modulo 3 term in A026601, and the n-th multiple of 3 in A026602. A026601 and A026602 appear to have the same sort of indexical properties. - _Matthew Vandermast_, Oct 06 2010
