2015-12-3 · The recursive definition of the Thue-Morse sequence is that . T_0 = 0 T_2n = T_n T_2n+1 = 1 - T_n A more direct definition is that the sequence from 0 to 2**m-1 and 2**m to 2**(m+1)-1 are binary complements. So 0 is followed by 1, 01 is followed by 10, 0110 is followed by 1001, and, skipping ahead a bit, 0110100110010110 is followed by 1001011001101001.
