FORMULA

Let the sequence 1, 0, 1, 1, 0, 0, 1, 0, 1, ... be defined to be the fixed point of the morphism 1->101 and 0->100, starting from a(1)=1 . The indices of 0 are 2, 5, 6, 8, 11, 14, 17, 18,..(this sequence with first term omitted ) . - Philippe Deléham, Jun 27 2006

After first term, these are the numbers of the form (3i+2)*3^j, where i >= 0, j >= 0. - Clark Kimberling, Oct 19 2016

MATHEMATICA

a[b_] := Table[Mod[n/b^IntegerExponent[n, b], b], {n, 1, 160}]

p[b_, d_] := Flatten[Position[a[b], d]]

p[3, 1] (* A026225 *)

p[3, 2] (* A026179 without initial 1 *)
