Query: Interacting Galaxies in Sparsely Populated Groups   We calculated the median values of the following parameters for 87 groups of
galaxies with three to eight components: the mean rms velocity of the galaxies
in the group, S_v = 166 km/s; the harmonic mean radius, R_h = 29 kpc; and the
mass-to-light ratio, M_vir/L = 33 Msun/Lsun. The M_vir/L ratio depends on the
population of the system, while S_v does not depend on R_h. To ascertain the
relationship between the activity of galaxies in groups and their morphological
composition and the effect of the environment on the evolutionary processes in
groups, we consider the fraction of galaxies with UV excess in the sample of
interacting galaxies in groups (6%), single peculiar galaxies (8%), and
isolated galaxies (4%) and their morphological composition. We also show that
the number of active galaxies decreases with increasing population of the group
of galaxies, while the frequency of occurrence of early-type (E/S0) galaxies
increases.
