The supercluster-void network V. Alternative evidence for its regularity

. We analyse the distribution of Abell clusters of galaxies to study the regularity of the supercluster-void network. We apply a new method sensitive to the geome-try of the location of clusters, and measure the goodness of regularity of the network. We find that the supercluster-void network resembles a cubical lattice over the whole space investigated. The distribution of rich superclusters is not isotropic: along the main axis of the network it is periodic with a step of length ≈ 130 h − 1 Mpc, whereas along the diagonal of the network the period is larger, as expected for a cubical lattice. This large-scale inhomogeneity is compatible with recent CMB data. of superclusters.
