speciality of the binary sequence $underline{100101100110100}101101001$












1












$begingroup$


One friend has given me this binary sequence and asked what is its speciality if we add next few terms to this sequence?

The binary sequence was:
$$color{blue}{underline{100101100110100}}101101001 dots$$
Hints Given: It's a Classical one.

So,could anyone please help me to recognise its speciality...

          Is it:




          The (opposite of the) Thue-Morse sequence.


          Start with $1 to 10 to 1001 to 10010110 to 1001011001101001$, where at each step the opposite of what is already there is added.
