a(n)=A062138(n+5, 5) = (n+5)!*binomial(n+10, 10)/5!.
E.g.f.: N(5;5, x)/(1-x)^16 with N(5;5, x) := sum(A062190(5, k)*x^k, k=0..5) = 1+50*x+450*x^2+1200*x^3+1050*x^4+252*x^5.
If we define f(n,i,x)= sum(sum(binomial(k,j)*stirling1(n,k)*stirling2(j,i)*x^(k-j),j=i..k),k=i..n) then a(n-10)=(-1)^n*f(n,10,-6), (n>=10). [From Milan Janjic, Mar 01 2009]
