In this paper we present results from numerically simulating the scalar sector of the minimal standard model on an F4 lattice. This lattice obeys Lorentz invariance to a higher degree than hypercubic lattices previously used in this context. The major result of our study is that if one is willing to tolerate cutoff effects up to about 3% in the WL-WL scattering cross section, the upper bound on the mass of the Higgs boson in the simplest F4 model is 590 GeV with an error of about 60 GeV.
