    They are quite similar to each other in overall size and shape, generally a few hundred kiloparsecs across, and moderately egg-shaped.
     They range in appearance from circular to quite elongated, but are quite similar to each other in overall size.
     They are similar to each other in shape, generally moderately egg-shaped, but range in size from 1 kiloparsec to several megaparsecs across.

     They exist only in extremely large "giant ellipticals," resulting from previous mergers, that are several megaparsecs across.
