%N Fifth column of triangle A075502.

%C The e.g.f. given below is Sum_{m=0..4} A075513(5,m)*exp(7*(m+1)*x)/4!.

%F a(n) = A075502(n+5, 5) = (7^n)*S2(n+5, 5) with S2(n, m) := A008277(n, m) (Stirling2).

%F a(n) = Sum_{m=0..4} A075513(5, m)*((m+1)*7)^n/4!.

%F G.f.: 1/Product_{k=1..5} (1 - 7*k*x).

%F E.g.f.: (d^5/dx^5)(((exp(7*x)-1)/7)^5)/5! = (exp(7*x) - 64*exp(14*x) + 486*exp(21*x) - 1024*exp(28*x) + 625*exp(35*x))/4!.

%Y Cf. A075923, A075925.
