%N A082139 A transform of C(n,5).
%C A082139 Sixth row of number array A082137. C(n,5) has e.g.f. (x^5/5!)exp(x). 
               The transform averages the binomial and inverse binomial transforms.
%F A082139 a(n)=(2^(n-1)+0^n/2)C(n+5, n)=sum{j=0..n, C(n+5, j+5)C(j+5, 5)(1+(-1)^j)/
               2 } G.f.: (1-6x+30x^2-80x^3+120x^4-96x^5+32x^6)/(1-2x)^6 E.g.f. (x^5/
               5!)exp(x)cosh(x) (preceded by 5 zeros).
%F A082139 ceil(binomial(n+5,5)*2^(n-1)). - Zerinvary Lajos (zerinvarylajos(AT)yahoo.com),
