The author presents the results of a numerical simulation of a universe dominated by cold dark matter. He adopts the inflationary background model with the density parameter Ω0 = 0.2. Primordial fluctuations are assumed to be adiabatic with a constant curvature power spectrum. The particle-mesh (PM) code with 643 particles on a 643 grid is used. Huge low-density regions and systems of all kinds of multiplicity appear in the present model. This model describes satisfactorily at least two aspects of the properties of structures in the Local Supercluster: the percolation properties and the distribution of high- and low-density regions.
