Smith, et. al. (2003) suggest the group is evolving to an elliptical dominated group and confirmed the tidal tail connections plus the visual extension to the NW from 4410-a possibly created by a supernova causing an expanding bubble in the ISM.
The galaxies on the right are NGC 4411-a (top) and NGC 4411-b (bottom). Both are classified as Sbdm with an approximate mag. 15 surface brightness, distance is 74 Mly. (Full scale image)
The faint object at upper center is not identified in any of the sources available to me.
