Some observational aspects of the orientation of galaxies
  We investigated the sample of galaxies belonging to the Tully groups of
galaxies. We analyzed the orientation of galaxies inside the group. We did not
found significant deviation from isotropy both in orientation of position
angles and angles $\delta_D$ and $\eta$ giving the spatial orientation of
galaxy planes. Moreover we analyzed consequences of different approximation of
"true shape" of galaxies and showed possible influence of this problem for
investigation of spatial orientation of galaxies. Implications of the obtained
results for theory of galaxy formation was discussed as well.
