Cumulative distributions of the values of the environmental densities around clusters for the smoothing length 4 h^-1 Mpc. Solid black line denote densities around multicomponent clusters (left panel), clusters with significant substructure (middle panel), and clusters with the peculiar velocities of their main galaxies larger than 250 km s^-1 (right panel). Dashed grey line denote densities around one-component clusters (left panel), clusters without significant substructure (middle panel), and clusters with the peculiar velocities of their main galaxies smaller than 250 km s^-1 (right panel). Upper row – distance interval 120 h^-1 Mpc  ≤ D ≤  180 h^-1 Mpc, lower row – distance interval 180 h^-1 Mpc  ≤ D ≤  300 h^-1 Mpc.
