  The probability distribution of the conductance Pc(g) at the Anderson
critical point is calculated. It is find that Pc(g) has a dip at small g in
agreement with epsilon expansion results. The Pc(g) for the 3d system is quite
different from the 2d quantum critical point of the integer quantum Hall
effect. The universality or not of these distributions is of central importance
to the field of disordered systems.
