Formula

From Chai Wah Wu, Jan 26 2020: (Start)

a(n) = 24*a(n-1) - 210*a(n-2) + 1012*a(n-3) - 3135*a(n-4) + 6732*a(n-5) - 10428*a(n-6) + 11880*a(n-7) - 9999*a(n-8) + 6160*a(n-9) - 2706*a(n-10) + 804*a(n-11) - 145*a(n-12) + 12*a(n-13) for n > 12.

G.f.: (-13*x^12 - 24419*x^11 - 1829674*x^10 - 26288999*x^9 - 114654375*x^8 - 178952070*x^7 - 101134044*x^6 - 16702950*x^5 + 371349*x^4 + 128425*x^3 + 1958*x^2 + 13*x - 1)/((x - 1)^12*(12*x - 1)). (End)
