Abstract
We present an efficient generator for the process e+e- --> 4 fermions + gamma through off-shell W pairs. It is based on a massless matrix el ement with leading O(m2) corrections. Only the resonant WW graphs are included. We have tested it against a matrix element without these app roximations and found agreement to within approximately 1% at LEPII en ergies.
