%N The sum of the weights of the stones-and-bones tilings of the (n,2n-4)-benzel, where each stone is given multiplicative weight 3.
%C See Problem 17 of the Propp article. It is conjectured that a(n) is 2-adically continuous as a function of n > 4.
%D J. Propp, Trimer covers in the triangular grid: twenty mostly open problems, to appear.
