  Six subclusters in the Coma cluster have been selected on the basis of a
hierarchical clustering method that takes the gravitational interaction among
galaxies into account. Of these, three main subclusters around the galaxies NGC
4889, NGC 4874, and NGC 4839 have been singled out. We have used the objective
statistical criterion applied by Vennik and Anosova in studies of close groups
of galaxies to evaluate each member included in a subcluster with a high
probability. Galaxies with a significant deficit of hydrogen HI, including
objects from the Bravo-Alfaro list,have been identified with members of the
subclusters, with the greatest number of them in the subclusters around NGC
4874 and NGC 4839. A quantitative estimate of the hydrogen deficit using the HI
index in the RCG3 catalog reveals a statistically significant excess value for
those galaxies that are members of the subclusters compared to the field
galaxies with a hydrogen deficit in the studied area of Coma cluster. A
substantial number of the spiral galaxies with a hydrogen deficit in the
subclusters turned out to be radio galaxies as well.
