On the cometary shape of compact groups of compact galaxies

It is shown that the brightest members of elongated, compact groups of compact galaxies (CGCGs) are located not in the central part of a group but at its edge. This suggests that compact groups of compact galaxies (n>8) have a cometary shape, with their opening angle being less than 60°, for the most part.Translated from Astrofizika, Vol. 39, No. 4, pp. 585–592, October–December, 1996.
