%N Numerators associated with denominators A000215(n) approximating the complementary Thue-Morse constant.

%C If in the sequence of numbers N for which A010060(N+2^n)=1-A010060(N) the odious (evil) terms are

%C replaced by 1's (0's), we obtain a 2^(n+1)-periodic binary sequence. These are the post-period

%C binary (base-2) digits of the complementary Thue-Morse constant 1-A014571 = 0.58754596635989240221663...,

%C which has a continued fraction and convergents 3/5, 7/12, 10/17, 47/80, 151/257, 801/1365,...

%C The a(n) are numerators of the convergents selected with denominators taken from A000215.
