Query: Flattening of Galaxies of Different Morphological Types in Subclusters
  of Coma   The dependence of flattening of galaxies on the density of galaxies in
subclusters selected around galaxies NGC4889, NGC4874 and NGC4839 in the Coma
cluster has been studied. The mean values of observed ratios of galaxy
diameters and histograms of their distributions indicate that in the central,
dense regions of subclusters E and S0 type galaxies are close to spheroidals.
Spiral galaxies in subcllusters are found with a hydrogen deficit that about 5
times exceeds the hydrogen deficit in spirals within the halo of the Coma
cluster. Most of spirals with a hydrogen deficit in the subcluster around NGC
4874 according to their 3-D coordinates are located closer to the south-east
edge of this subcluster near an extended gas filament in the x-ray region. This
may indicate over the move of this subcluster toward the central condensation
of faint galaxies in the Coma cluster for a possible merge with it.
