DESCRIPTION:Speakers: Irina Arkhangelskaja   (MEPhI)\nPreliminary results 
 of the investigation of the properties of 7 clusters of galaxies from CfA2
  redshift survey are discussed in the presented poster. Clusters 933\, 142
 \, 1046\, and 1652\, which have several pecularities of the spatial distri
 butions of galaxies. Moreover\, these objects have high-energy gamma assoc
 iations on Fermi/LAT data (4FGL J1144.9 + 1937\, 4FGL J0152.2 + 3714\, 4FG
 L J1230.8 + 1223 and 4FGL J1653.8 + 3945. The investigation of the spatial
  distribution and other characteristics of 933\, 1242\, 88\, 142\, 1046\, 
 1101 galaxy clusters shows gravitational lensing effect. Investigation of
  high-energy gamma-emission of galaxies and peculiarities of its motion in
  groups allows studying properties of such inhomogeneities and understandi
 ng of its nature possibly caused by dark matter. Moreover\, common observa
 tions of such clusters by orbital gamma-ray telescopes with high angular r
 esolution and ground-based Cherenkov air-shower experiments could possibly
  clarify the type of gravitational lenses.\n\nhttps://indico.particle.meph
