QED contributions to electron g-2

In this paper I briefly describe the results of the numerical evaluation of the mass-independent 4-loop contribution to the electron g -2 in QED with 1100 digits of precision. In particular I also show the semi-analytical fit to the numerical value, which contains harmonic polylogarithms of e iπ/3 , e 2iπ/3 and e iπ/2 one-dimensional integrals of products of complete elliptic integrals and six finite parts of master integrals, evaluated up to 4800 digits. I give also some information about the methods and the program used.
