%e As a word, A010060 = 0110100110010110100101100..., and replacing each 010 by 0 gives 0111011011111110011101101110...

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

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

%t w1 = StringReplace[w, {"010" -> "0"}]

%t st = ToCharacterCode[w1] - 48 (* A286055 *)

%t Flatten[Position[st, 0]] (* A286056 *)

%t Flatten[Position[st, 1]] (* A286057 *)

%Y Cf. A010060, A286056, A286057.
