| Abstract: | The structures of compact groups of galaxies are compared with the structures of rich clusters of galaxies. It was established that there are structural similarities between these two types of clusters of galaxies. It is imaginable that these structures are typical for all such complexes of galaxies and that the different structures are due to different initial conditions at the beginning of their evolution. For a final answer on this question it is necessary to accumulate more observational material with respect to the distribution of galaxies in such clusters. As part of a larger programme the present paper contains the derived number-density distributions and core radii for ten clusters. |
