Some properties of galaxy structures
  We analysed some properties of galaxies structures based on PF Catalogue of
galaxy structures (Panko & Flin 2006) and Tully NBG Catalog (Tully 1988) At
first, we analyzed the orientation of galaxies in the 247 optically selected
rich Abell clusters, having in the area considered as cluster at least 100
members. The distribution of the position angles of the galaxy as well as two
angles describing the spatial orientation of galaxy plane were tested for
isotropy, applying three statistical tests. We found that anisotropy increases
with the number of member galaxies, which means there exists the relation
between anisotropy and cluster richness. We do not find connection of galaxy
alignment and Bautz - Morgan morphological type of parent cluster. The
statistically marginal relation between velocity dispersion and cluster
richness was observed. However it was found that velocity dispersion decreases
with Bautz - Morgan type at almost $3 \sigma$ level. Separately we analyzed
ellipticities for 6188 low redshift ($z < 0.18$) poor and rich galaxy
structures which have been examined along with their evolution. Finally we
analysed the Binggeli effect. The orientation of galaxy groups in the Local
Supercluster (LSC), is strongly correlated with the distribution of
neighbouring groups in the scale till about 20 Mpc. During analyses of galaxy
structures from PF catalogue the situation was quite different. The efect is
observed only for more elongated structures ($e \le 0.3$). The range of the
distance in which the effect was observed, was estimated as about $60 h^{-1}
MPc$.
