%N Decimal expansion of d - log(d-e) where d is Feigenbaum's bifurcation velocity constant (A006890, delta constant) and e is Euler's constant.

%C From Plouffe's Inverter: log(s)^2 * a^2 * sin(1)^1 = 4.000900694855076... where s is Sierpinski's constant (A062089) and a is Feigenbaum's reduction parameter (A006891, alpha constant). 20 + Pi - exp(Pi) = .00090002081...
