According to the standard model of cosmology the visible, baryonic matter ofgalaxies is embedded in dark matter haloes, thus extending the mass and thesize of galaxies by one to two orders of magnitude. Taking into accountdynamical friction between the dark matter haloes, the nearby located M81 groupof galaxies as well as the Hickson compact groups of galaxies are hereinvestigated with regard to their dynamical behaviour. The results of theemployment of the Markov Chain Monte Carlo method and the genetic algorithmshow statistically substantial merger rates between galaxies, and long livingconstellations without merging galaxies comprise - apart from very fewinstances - initially unbound systems only. This result is derived based onthree- and four-body calculations for a model of rigid Navarro-Frenk-Whiteprofiles for the dark matter haloes, but verified by the comparison to randomlychosen individual solutions for the M81 galaxy group with high-resolutionsimulations of live self-consistent systems (N-body calculations). Inconsequence, the observed compact configurations of major galaxies are a veryunlikely occurence if dark matter haloes exist.
