%N Sixth column of triangle A075503.

%C The e.g.f. given below is Sum_{m=0..5} (A075513(6,m)*exp(8*(m+1)*x))/5!.

%F a(n) = A075503(n+6, 6) = (8^n)*S2(n+6, 6) with S2(n, m) := A008277(n, m) (Stirling2).

%F a(n) = Sum_{m=0..5} (A075513(6, m)*((m+1)*8)^n)/5!.

%F G.f.: 1/Product_{k=1..6} (1 - 8*k*x).

%F E.g.f.: (d^6/dx^6)(((exp(8*x)-1)/8)^6)/6! = (-exp(8*x) + 160*exp(16*x) - 2430*exp(24*x) + 10240*exp(32*x) - 15625*exp(40*x) + 7776*exp(48*x))/5!.

%t With[{m = 6}, Array[8^(# - m) StirlingS2[#, m] &, 14, m]] (* _Michael De Vlieger_, Dec 24 2017, after _Indranil Ghosh_ at A075503 *)

%Y Cf. A076005, A076007.
