Query: The three-loop beta function of SU(N) lattice gauge theories with Wilson
  fermions   We calculate the third coefficient of the lattice beta function associated
with the Wilson formulation for both gauge fields and fermions. This allows us
to evaluate the three-loop correction (linear in $g_0^2$) to the relation
between the lattice Lambda-parameter and the bare coupling $g_0$, which is
important in order to verify asymptotic scaling predictions. Our calculation
also leads to the two-loop relation between the coupling renormalized in the
MSbar scheme and $g_0$.
  The original version of this paper contained a numerical error in one of the
diagrams, which has now been corrected. The calculations, as well as the layout
of the paper have remained identical, but there are some important changes in
the numerical results.
