[tex]li(x)=\gamma+ln(ln(x))+\sum^{\infty}_{n=1}\frac{ln(x)^n}{n*n!}[/tex]

where [tex]\gamma[/tex] is the Euler–Mascheroni constant.

This infinite series is a continuous function and maps x to li(x) on a 1-to-1 basis.

Therefore, in theory there should be an inverse function of li, right? But I'm having difficulty finding it.

Thanks for any help guys :)
