Scientific paper

A positive spatial correlation is observed among a complete sample of superclusters on a scale of 100/h Mpc. The correlation is significant at about the 95-99 percent confidence level, suggesting the possible existence of the largest structures yet detected. The correlation appears to be stronger than that of galaxies and galaxy clusters, indicating a continuation in the increasing strength of clustering with richness. The validity of the correlation suggested here could be tested at a high level of statistical significance by obtaining the redshift of all 1682 rich clusters in the complete Abell catalog, corresponding to redshifts of z not greater than about 0.2.
