%N Fourth diagonal of second-order Eulerian triangle A008517. Fourth column (m=3) of triangle A112007.

%F a(n)=A112007(n+3, 3), n>=0.

%F a(n)= (n+7)*a(n-1) + (n+1)*A002539(n+1), n>=1, a(0)=1.

%F Contribution from _Johannes W. Meijer_, Oct 16 2009: (Start)

%F a(n) = sum((-1)^(n+k)*binomial(2*n+9,k)*stirling1(n-k+8,4-k), k=0..3)

%F (End)

%e 1452= a(2) = 9*52 + 3*328.

%Y Cf. A002539 (3rd diagonal of A008517; third column of A112007).

%Y Contribution from _Johannes W. Meijer_, Oct 16 2009: (Start)
