EXAMPLE
As a word, A010060 = 0110100110010110100101100..., and replacing each 1010 by 1 gives 0110110010110101100110110010...
MATHEMATICA
s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {1, 0}}] &, {0}, 9] (* A010060 *)
w = StringJoin[Map[ToString, s]]
w1 = StringReplace[w, {"1010" -> "1"}]
st = ToCharacterCode[w1] - 48 (* A286400 *)
Flatten[Position[st, 0]] (* A286401 *)
Flatten[Position[st, 1]] (* A286402 *)
