N We show how the standard domain wall action can be simply modified to
allow arbitrarily exact chiral symmetry at finite fifth dimensional extent. We
note that the method can be used for both quenched and dynamical cal-
culations. We test the method using smooth and thermalized gauge field
configurations. We also make comparisons of the performance (cost) of the
domain wall operator for spectroscopy compared to other methods such as
the overlap-Dirac operator and find both methods are comparable in cost.
