Previous numerical simulations have shown that under certain conditions rotating gas clouds break up in two equal parts. The authors explore the consequences, if this process continues and a planar, equal mass four-body system forms. The results of the four-body calculations are used in Monte Carlo simulation of fragmentation of a rotating gas cloud in a galactic nucleus. Then it appears possible that clusters of large numbers of objects form; the dynamical evolution of these clusters has been calculated. The results were applied to ejection of supermassive objects from galactic nuclei. The authors find that several statistical properties of double radio sources may be understood as resulting from the fragmentation process.
