%N Continued fraction expansion of the value of Minkowski's question mark function at Levy's constant (Exp[Pi^2/(12*Log[2])], A086702).
%C a[92] has over 150 decimal digits, making 750332738256083509758042341909438953923620244270237443771885409340366143805720089/2^267 an excellent approximation to the constant.
