The anomalous magnetic moment of the electron is one of the physical quantities measured with the highest precision. Such a high precision demands a similar precision in the theoretical evaluations in order to obtain stringent tests of QED. I will show the results of the twenty-year long project of the 1100-digit evaluation of the mass-independent four-loop QED corrections to the electron g-2. I will describe the methods used and discuss the consequences of this result on the QED tests and the determination of the fine structure constant.
