3.4 Summary

Searching for compelling evidence of mergers, tidal stripping, and accretion has not proven easy. A case can perhaps be built, but it is likely to rest on a large body of circumstantial evidence. More surface photometry for cluster luminosity functions, galaxy sizes and colors, and intergalactic light measurements are crucial to future progress in this area.
