Models for the Friedmann Universe are constructed from 5, 16, or 600 dust-filled tetrahedrons connected so as to form a closed space. Using the techniques of Regge calculus the time development of these model universes is determined and the results compared with the standard analytic solution for an isotropic dust-filled universe.
