  The evidence is becoming strong that the luminosity function of galaxies
varies with environment. Higher density, more dynamically evolved regions
appear to have more dwarfs per giant. The situation is becoming clearer as a
result of wide field imaging surveys with the Canada-France-Hawaii and Subaru
telescopes and spectroscopy of faint dwarfs with the Keck telescope. We report
here on extensive observations of the small but dense NGC 5846 Group. The faint
end of the luminosity function rises relatively steeply in this case.
