%N A120572 Smallest area of any triangle with integer sides a<=b<=c and inradius 
               n.
%C A120572 a(n) == 0 (mod 6).
%C A120572 Empirically, 3*sqrt(3) < a(n)/n^2 <= 6. The lower bound is provably tight, 
               the upper bound seems to be achieved infinitely often, e.g, for prime 
               n >= 5.
