Table of n, a(n) for n=0..14.

Formula

a(n)=A112007(n+4, 4), n>=0.

a(n)= (n+9)*a(n-1) + (n+1)*A112008(n), n>=1, a(0)=1.

Contribution from Johannes W. Meijer, Oct 16 2009: (Start)

a(n) = sum((-1)^(n+k+1)*binomial(2*n+11,k)*stirling1(n-k+10,5-k),k=0..4)

(End)

Example

5610= a(2) = 11*114 + 3*1452.
