FORMULA
From Wesley Ivan Hurt, Oct 28 2014: (Start)
G.f.: 4096*(531441 + 68712568003*x + 22404773377311*x^2 + 859316242027205*x^3 + 8673413722667370*x^4 + 30946876621062078*x^5 + 44108689210889694*x^6 + 25884027384156618*x^7 + 5972410776815445*x^8 + 467792550632655*x^9 + 8736164034131*x^10 + 13841233953*x^11 + 4096*x^12) / (1-x)^13.
a(n) = 13*a(n-1)-78*a(n-2)+286*a(n-3)-715*a(n-4)+1287*a(n-5)-1716*a(n-6)+1716*a(n-7)-1287*a(n-8)+715*a(n-9)-286*a(n-10)+78*a(n-11)-13*a(n-12)+a(n-13).
