%N A093603 Decimal expansion of d/2, where d^2=pi/sqrt(3).
%C A093603 d/2=sqrt{pi/sqrt(3)}/2 gives the length of the smallest stroke halving 
               the unit-sided equilateral triangle. From A093602, it is plain that 
               d^2<2, i.e. (d/2)^2<1/2=square of the bisecting line segment parallel 
               to triangle's side. d/2 actually is the arc subtending angle pi/3 
               about center of circle with radius D/2, where D^2=3/d^2. Since pi/
