  The production of four fermions plus a visible photon in electron-positron
collisions is analyzed, with particular emphasis on the LEP2 energy range. The
study is based on the calculation of exact matrix elements, including the
effect of fermion masses. In the light of the present measurements performed at
LEP, triple and quartic anomalous gauge couplings are taken into account. Due
to the presence of a visible photon in the final state, particular attention is
paid to the treatment of higher-order QED corrections. Explicit results for
integrated cross sections and differential distributions are shown and
commented. The features of the Monte Carlo program WRAP, used to perform the
calculation and available for experimental analysis, are described.
