We study Fano threefolds with terminal Gorenstein singularities admitting a 'minimal' action of a finite group. We prove that under certain additional assumptions such a variety contains no planes. We also obtain upper bounds for the number of singular points of certain Fano threefolds with terminal factorial singularities.
