Abstract:
    We study the whole-sky distribution of rich clusters of galaxies up to
    the distance z~0.1 and present catalogues of superclusters and
    cluster-defined voids. The data on clusters, superclusters and voids
    show the presence of the characteristic scale of 130h^-1^Mpc in the
    supercluster-void network, found earlier by Broadhurst et al.
    (1990Natur.343..726B) from a one-dimensional study. This scale has
    been detected in the distribution of clusters of richnesses R=0 and
    R>=1. We perform tests to study the influence of projection effects.
    The clusters that do not belong to superclusters are located in the
    vicinity of superclusters and form their outlying parts.
    We compare the distribution of ACO clusters with that of APM clusters.
    The APM clusters determine a smaller scale: 100h^-1^Mpc. We discuss
    the possible reasons for this difference.

        got screwed up and give wrong Abell cluster names as members
        for superclusters.
