A significant difference is noted, however, between the distribution of axis ratios for a sample of BCGs and for a sample of second-brightest cluster ellipticals. It is also noted, in partial support for a hypothesized competition of BCGs for cluster galaxies that would otherwise merge with the second-brightest cluster ellipticals, that the shape of a merger remnant can reflect the relative masses of the progenitor as well as the angular momentum of the merging system.
