On the Large-Scale Structure of the Universe as given by the Voronoi   Diagrams
  The size distributions of 2D and 3D Voronoi cells and of cells of $V_p(2,3)$,--2D cut of 3D Voronoi diagram--are explored, with the single-parameter (re-scaled) gamma distribution playing a central role in the analytical fitting. Observational evidence for a cellular universe is briefly reviewed. A simulated $V_p(2,3)$ map with galaxies lying on the cell boundaries is constructed to compare, as regards general appearance, with the observed CFA map of galaxies and voids, the parameters of the simulation being so chosen as to reproduce the largest observed void size.
