Description
In this talk I will describe the results of evaluation up to 1100 digits of precision of the mass-independent contribution of the 891 4-loop Feynman diagrams contributing to the electron g-2 in QED.
I will show the analytical expressions fitted to the high-precision values,
which contain polylogarithms of sixth-root of unity and one-dimensional integrals of products of complete elliptic integrals.
I will discuss also some technical aspects of my program SYS used to perform all the calculations.
