%N Solution to the Dancing School Problem with 12 girls and n+12 boys: f(12,n).
%C f(g,h) = per(B), the permanent of the (0,1)-matrix B of size g X g+h with b(i,j)=1 if and only if i <= j <= i+h. See A079908 for more information.
%C For fixed g, f(g,n) is polynomial in n for n >= g-2. See reference.
