The large-scale structure of the Universe as delineated by clusters of galaxies is dominated by a network of alternate superclusters and voids - or cells, superclusters forming cell walls and voids cell interiors. The cellular structure is surprisingly regular, the mutual distance between high-density peaks of neighbouring superclusters is dt ≍ 130 h-1Mpc. Voids defined by rich clusters of galaxies are not empty but contain filaments of galaxies and systems of galaxies of lower richness. Bright galaxies inside cluster defined voids are dominantly spirals whereas bright galaxies in void walls are dominantly ellipticals. The whole picture shows the presence of a hierarchy of systems of galaxies and voids. The cellular structure with alternate high- and low-density regions is expected for a two-power law density spectrum with a maximum near the observed scale dt.
