This entirely solves the problem. But I don't know what branch of the Lambert function to use as of now.
Does anyone have a good formula for how the various branches of Lambert relate to the Lambert formula for the inverse of:
\[
g(y) = y^{1/y}\\
\]
Hmm, just to make sure: you know that LambertW (though without branch-index so far) is in Pari/GP? (I think in the 2.14-versions (alpha,experimental) they have it with branchindex) . And even better, the implementation in Pari/GP by our (former?) member mike3 - a real good one as it seems to me, allowing branch-indexing.
