As the missing complement to existing studies of shell galaxies, we carried

stellar shell system within a giant elliptical galaxy. We discuss the effect of
a phenomenon possibly associated with the galaxy merger simulations --- a
presence of multiple generations of shells.Comment: 2 pages, 1 figure, to appear in the Proceedings of JENAM 2010,
