Filaments of galaxies and Voronoi diagrams
  The intersections between a spherical shell and the faces of Voronoi's
polyhedrons are numerically evaluated. The nodes of these intersections are the
points that share the same distances from three nuclei. The nodes are assumed
to be the places where we will find clusters of galaxies. The cosmological
environment is given by the coupling between the number of galaxies as function
of the redshift and the LCDM cosmology.
