COMMENT

The e.g.f. given below is sum(A075513(6,m)*exp(2*(m+1)*x),m=0..5)/5!.

FORMULA

a(n)=A075497(n+6, 6)=(2^n)*S2(n+6, 6) with S2(n, m) := A008277(n, m) (Stirling2).

a(n)= sum(A075513(6, m)*((m+1)*2)^n, m=0..5)/5!.

G.f.: 1/product(1-2*k*x, k=1..6).

E.g.f.: diff((((exp(2*x)-1)/2)^6)/6!, x$6) = (-exp(2*x)+160*exp(4*x)-2430*exp(6*x)+10240*exp(8*x)-15625*exp(10*x)+7776*exp(12*x))/5!.

CROSSREFS
