a(n) = 23*a(n-1) - 187*a(n-2) + 825*a(n-3) - 2310*a(n-4) + 4422*a(n-5) - 6006*a(n-6) + 5874*a(n-7) - 4125*a(n-8) + 2035*a(n-9) - 671*a(n-10) + 133*a(n-11) - 12*a(n-12) for n > 11.
G.f.: (11*x^11 + 12166*x^10 + 573012*x^9 + 5414629*x^8 + 15268726*x^7 + 14414356*x^6 + 4151488*x^5 + 119218*x^4 - 35849*x^3 - 946*x^2 - 12*x + 1)/((x - 1)^11*(12*x - 1)). (End)
