[seqfan] A063747 sign of power series expansion of the Gamma function

[Sean A. Irvine]

Hi,

I believe the terms in A063747 are incorrect for n>=46.

https://oeis.org/A063747

My attempts to reproduce the calculation in Maple and using constructible
reals in Java both yield a coefficient, like -0.44458...e-38 * x^46, from
which a(46) should be -1 rather than 1.

Is someone able to make an independent check?

I was unable to run the existing Pari program beyond n=15, but I assume
there is some way to tell Pari to try harder?

(I previously emailed the author of the sequence, but received no response.)

Sean.
