EXAMPLE

As a word, A010060 = 0110100110010110100101100..., and replacing each 1101 by 1 gives 0100110010100101100...

MATHEMATICA

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

w = StringJoin[Map[ToString, s]]

w1 = StringReplace[w, {"1101" -> "1"}]

st = ToCharacterCode[w1] - 48 (* A286339 *)

Flatten[Position[st, 0]] (* A286340 *)

Flatten[Position[st, 1]] (* A286341 *)
