A systematic and automatic classification of groups of galaxies has been made only in two dimensions up to now (Turner and Gott, 1976). They investigated the projected density of galaxies at the sky. in this analysis one can correct for foreground and background galaxies and superimposed groups only statistically. the properties of the groups and their member galaxies will often not be recognized correctly. Therefore, a three dimensional analysis is proposed.
