A Conjectured Integer Sequence Arising From the Exponential Integral

Richard P. Brent, M. L. Glasser, Anthony J. Guttmann

Let $f_{0} (z) = exp (z / (1 - z))$ , $f_{1} (z) = exp (1/ (1 - z)) E_{1} (1/ (1 - z))$ , where $E_{1} (x) = \int_{x}^{\infty} e^{- t} t^{- 1} d t$ . Let $a_{n} = [z^{n}] f_{0} (z)$ and $b_{n} = [z^{n}] f_{1} (z)$ be the corres…
