%N A097301 Numerators of rationals used in the Euler-Maclaurin type derivation of 
               Stirling's formula for N!.
%C A097301 Denominators are given in A097302.
%C A097301 The e.g.f. sum( A(2*n+1)*(x^(2*n+1))/(2*n+1)!,n=0..infinity) appears 
               in the Stirling-formula derivation for N! with x=1/N in the exponent 
               and the formula for A(2*n+1):=a(n)/A097302(n), n>=0, is given below. 
               For Stirling's formula see A001163 and A001164.
%C A097301 The rationals A(2*n+1) = B(n):= (2*n)!*Bernoulli(2*(n+1))/(2*(n+1)) = 
               a(n)/A097304(n) with A(2*n):=0 are the logarithmic transform of the 
               rational sequence {A001163(n)/A001164(n)} (inverse of the sequence 
               transform EXP)
