%N The continued fraction of the positive constant r < sqrt(3) such that the partial quotients equal the integer floor of the powers of r.
%e This constant r, found in the interval (1, sqrt(3)), satisfies the continued fraction:
%e r = [1; [r], [r^2], [r^3], [r^4], ..., floor(r^n), ...], more explicitly:
%e r = [1; 1, 2, 4, 8, 13, 23, 39, 67, 113, 191, 324, 548, 928, ...] where
%e r = 1.691595419636107091520608953850126286827042452195819302381...
%e See A227233 for another constant that satisfies a continued fraction of the same construction but is found in the interval (sqrt(3), 2).
