%F G.f.: x*(128 + 43792327*x + 5240462124*x^2 + 90099630276*x^3 + 429789855348*x^4 + 709564273194*x^5 + 429789855348*x^6 + 90099630276*x^7 + 5240462124*x^8 + 43792327*x^9 + 128*x^10) / (1 - x)^12.

%F a(n) = 12*a(n-1) - 66*a(n-2) + 220*a(n-3) - 495*a(n-4) + 792*a(n-5) - 924*a(n-6) + 792*a(n-7) - 495*a(n-8) + 220*a(n-9) - 66*a(n-10) + 12*a(n-11) - a(n-12) for n>11.
