  We have derived the galaxy luminosity function (GLF) in the cluster of
galaxies Abell 496 from a wide field image in the I band. A single Schechter
function reproduces quite well the GLF in the 17 <= I_{AB} <= 22 (-19.5 <= M_I
<= -14.5) magnitude interval, and the power law index of this function is found
to be somewhat steeper in the outer regions than in the inner regions. This
result agrees with the idea that faint galaxies are more abundant in the outer
regions of clusters, while in the denser inner regions they have partly been
accreted by larger galaxies or have been dimmed or even disrupted by tidal
interactions.
