Description
We know from previous studies that the symetries of the
twisted Q-symmetric lattice theory are particularly powerful
in terms of protecting the long distance effective theory from unwanted
renormalizations. Here, it will be shown that rescalings of the
lattice fields imply that only two fine-tunings are required,
so that the N=4 theory is on a similar footing to clover fermions
in lattice QCD. We also provide a blocking scheme that
preserves the symmetries. We discuss this in relation to our
recent result that restoring any of the discrete R symmetries
is sufficient to obtain the correct continuum limit. An early
numerical study of this issue is discussed. We conclude with
prospects for a Monte Carlo renormalization group involving our
blocking scheme.
