EXAMPLE
As a word, A010060 = 0110100110010110100101100..., and replacing each 1001 by 1 gives 011011011010111011011101011011...
MATHEMATICA
s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {1, 0}}] &, {0}, 9] (* A010060 *)
w = StringJoin[Map[ToString, s]]
w1 = StringReplace[w, {"1001" -> "1"}]
st = ToCharacterCode[w1] - 48 (* A284932 *)
Flatten[Position[st, 0]] (* A284933 *)
Flatten[Position[st, 1]] (* A284934 *)
