Description
The QED scattering amplitude and cross section of $\gamma \gamma \rightarrow \gamma \gamma \gamma \gamma $ are calculated. The lowest order of this process appears in sixth order of the S-Matrix in which each photon interact with the other by creation of pair massive virtual fermions in the vacuum. This can be applied to calculation of the sixth-rank vacuum polarization tensor vector boson.
