The galaxy survey based on observations from the Automatic Plate Measuring (APM) machine is treated with an objective selection algorithm to derive a catalog of rich clusters of galaxies. Redshifts are presented for about 200 APM clusters with redshifts of less than approximately 0.1, and the mean space density overall is found to be four times the value for Abell clusters for which R is at least one. The spatial correlation given for the subsample is shown to be consistent with the results predicted by the conventional cold-dark-matter model. The APM cluster catalog is found to be more homogeneous than the Abell sample without large-scale anisotropies in the redshift-space correlation function. The present results demonstrate that more clustering can be found at scales of more than 10/h Mpc than is suggested in the standard model for cold dark matter.
