EXAMPLE

As a word, A286052 = 01000110000000100100..., in which 0 is in positions 1,3,4,5,3,...

MATHEMATICA

s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {1, 0}}] &, {0}, 9] (* Thue-Morse, A010060 *)

w = StringJoin[Map[ToString, s]]

w1 = StringReplace[w, {"101" -> "0"}]

st = ToCharacterCode[w1] - 48 (* A286052 *)

Flatten[Position[st, 0]]  (* A286053 *)

Flatten[Position[st, 1]]  (* A286054 *)

CROSSREFS
