FORMULA
a(n) = (n!/10!)*Stirling2(n-2, n-10). - Vladeta Jovovic, Jan 28 2004
a(n) = n! * (n-10)*(n-9)*(n-8)*(n-7)*(n-6)*(n-5)*(n-4)*(n-3)*(n-2)*(135*n^7 - 8190*n^6 + 211050*n^5 - 2991660*n^4 + 25164055*n^3 - 125425110*n^2 + 342426104*n - 394205184) / 5056584744960000. - Vaclav Kotesovec, Jul 25 2014
