Production of four leptons in electroweak $\gamma\gamma$ interactions
  Detailed numerical analysis of four charged leptons photoproduction in frame of standard theory of electroweak interaction is presented. Total and differential cross sections are obtained and investigated using the Monte-Carlo method of numerical integration. Different energies of initial photons (60-2000 GeV in c.m.s.) as well as the definite and averaged spin states of interacting particles are considered. A set of kinematical cuts of linear collider experiments is discussed.
