We analyze the distribution of Abell clusters of galaxies to study the regularity of the supercluster-void network. We apply a new method, the regularity periodogram, that is sensitive to the geometry of the location of clusters, and measure the regularity of the network. We find that the supercluster-void network resembles a cubic lattice over the entire volume considered (out to the distance of 350 h-1 Mpc). The distribution of clusters in rich superclusters is not isotropic: it is periodic along a cubic lattice approximately aligned with the supergalactic coordinates . This large-scale inhomogeneity does not contradict recent CMB data, but its theoretical explanation remains a challenge.
Key words: cosmology: observations / cosmology: large-scale structure of the Universe
