EXAMPLE
|
G.f.: A(x) = 1 + x + 2*x^2 + 5*x^3 + 16*x^4 + 62*x^5 + 298*x^6 +...
where the exponential:
A(x) = exp(x + 3*x^2/2 + 10*x^3/3 + 43*x^4/4 + 216*x^5/5 + 1326*x^6/6 +...)
and the product:
1/A(x) = (1 - x)(1 - x^2)(1 - 3*x^3)(1 - 10*x^4)(1 - 43*x^5)(1 - 216*x^6)*...
generate A(x) using the same coefficients (after intial term):
A157313=[1,1,3,10,43,216,1326,9283,74667,672085,6730098,74031079,...].
