%N Decimal expansion of lim_{n->infinity} (1 - 1/2)^((1/2 - 1/3)^(...^(1/(2n-1) - 1/(2n)))).
%C The sequence of real values x(n) = (1 - 1/2)^((1/2 - 1/3)^(...^(1/n - 1/(n+1)))) converges to two different limits depending on whether n is even or odd. This integer sequence gives the decimal expansion of the lower limit, to which the odd-indexed terms of {x(n)} converge.
