A detailed reinvestigation of the Coma cluster basing on enlarged observational material of number density distributions and radial velocities of galaxies as well as radio and x‐ray data is performed and supports our previous conclusion that this cluster possesses a substructure. This substructure is in the south‐western region of the cluster and produces the impression of an elongated cluster structure in the direction of the bridge between Coma and A 1367. A 1656 seems to be a cD‐like cluster with NGC 4874 as the only dominating giant central galaxy.
