FORMULA
a(n) = 21*a(n-1) - 110*a(n-2) + 3*9^n - 2*6^n, n >= 2. - Vincenzo Librandi, Mar 13 2011
a(n) = -25*10^(n+1) + 11^(n+3)/10 - 3*6^(n+1)/5 + 3*9^(n+2)/2. - R. J. Mathar, Mar 18 2011
a(n) = 36*a(n-1) - 479*a(n-2) + 2784*a(n-3) - 5940*a(n-4); a(0)=1, a(1)=36, a(2)=817, a(3)=14952. - Harvey P. Dale, Jan 16 2013
