COMMENTS

The e.g.f. given below is sum(A075513(5,m)*exp(6*(m+1)*x),m=0..4)/4!.

FORMULA

a(n)=A075501(n+5, 5)=(6^n)*S2(n+5, 5) with S2(n, m) := A008277(n, m) (Stirling2).

a(n)= sum(A075513(5, m)*((m+1)*6)^n, m=0..4)/4!.

G.f.: 1/product(1-6*k*x, k=1..5).

E.g.f.: diff((((exp(6*x)-1)/6)^5)/5!, x$5) = (exp(6*x)-64*exp(12*x)+486*exp(18*x)-1024*exp(24*x)+625*exp(30*x))/4!.

CROSSREFS

Cf. A075917, A075919.
