Some features of a program e e tt6 f for top quark pair production and
decay into six fermions at linear colliders are discussed. Lowest order standard
model predictions for cross sections of some six fermion channels and
for the top quark decay width are confronted with the predictions obtained
within a model with an anomalous Wtb coupling. The question of whether
non doubly resonant background can easily be reduced by imposing kinematical
cuts is addressed.
