Groups of galaxies may constitute an excellent laboratory for the study of galaxy interactions. These should naturally be more spectacular in the apparently densest groups, known as “compact groups”, presumably the densest isolated regions in the Universe. The theoretical question that arises is what is the dynamical evolution of a dense group?, while a more down-to-earth question is are compact groups as dense as they appear? I will attempt here to answer both of these questions in turn, basically summarizing two contributions to an earlier conference (Mamon 1990a,b).
