%e As a word, A010060 = 0110100110010110100101100..., and replacing each 0011 by 1 gives 01101100101101001011101100101110...

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

%t w = StringJoin[Map[ToString, s]]

%t w1 = StringReplace[w, {"0011" -> "1"}]

%t st = ToCharacterCode[w1] - 48 (* A284627 *)

%t Flatten[Position[st, 0]] (* A284684 *)

%t Flatten[Position[st, 1]] (* A284685 *)

%Y Cf. A010060, A284684, A284685.
