Scientific paper

Generalized techniques for determining density enhancements in redshift space are presented, and one of these techniques is used to examine the effects of varying selection criteria on the dynamical parameters defined for groups of galaxies. There is a broad range of selection parameters which yields well defined and well behaved groups. A whole sky catalog of nearby groups with outer number density enhancement exceeding 20 is presented; the median M/L for these groups is approximately 170, corresponding to a cosmological density Omega = 0.1. A two-dimensional projection of several contours near the Virgo cluster is examined, and the clustering is found to exhibit both concentric and hierarchical structure.
