This is my first posting to seqfan, prompted by a message from John
Conway....I trust it got through to the whole list...

1. ProductLog in Mathematica IS exactly LambertW

2. Sum[((-n)^(n - 1)*z^n)/n!, {n, 1, Infinity}]  is indeed the series for=

ProductLog, as Walter Meussen said.

3. Corless and Borwein (jborwein at, rcorless at
have some new results relating the series expansion for ProductLog to
Stirling's them for details...perhaps their preprint =
on a web page.
