FORMULA
|
a(n)=A075501(n+6, 6)=(6^n)*S2(n+6, 6) with S2(n, m) := A008277(n, m) (Stirling2).
a(n)= sum(A075513(6, m)*((m+1)*6)^n, m=0..5)/5!.
G.f.: 1/product(1-6*k*x, k=1..6).
E.g.f.: diff((((exp(6*x)-1)/6)^6)/6!, x$6) = (-exp(6*x)+160*exp(12*x)-2430*exp(18*x)+10240*exp(24*x)-15625*exp(30*x)+7776*exp(36*x))/5!.
