Recent studies of the spatial distribution of galaxies and of clusters indicate that practically all clusters and a vast majority of galaxies are concentrated into supercusters. The space between superclusters has no rich clusters and very few galaxies. The whole structure is cellular, with cell walls formed from sheetlike superclusters and the empty cell interiors being huge voids.

In this presentation we show how the observed distribution of clusters, and the Local Supercluster in particular, are part of a cellular structure and suggest that the entire pattern of superclustering is cellular. Our study is based on the recently completed CFA redshift survey. All other available redshifts are also used, including cluster redshifts where available.
