%N {110->1}-transform of the Thue-Morse word A010060.
%C This is also the {100->0}-transform of A010060.
%H Clark Kimberling, <a href="/A286049/b286049.txt">Table of n, a(n) for n = 1..10000</a>
%e As a word, A010060 = 0110100110010110100101100..., and replacing each 011 by 1 gives 01100101011001010110010101011001...
%t s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {1, 0}}] &, {0}, 9] (* Thue-Morse, A010060 *)
%t w = StringJoin[Map[ToString, s]]
%t w1 = StringReplace[w, {"110" -> "1"}]
%t st = ToCharacterCode[w1] - 48 (* A286049 *)
%t Flatten[Position[st, 0]] (* A286050 *)
%t Flatten[Position[st, 1]] (* A286051 *)
%Y Cf. A010060, A286050, A286051.
