Distribution of galaxies in different global density regions in the A2142 supercluster in the sky plane. Red filled circles denote galaxies in region of global density D8 ≥ 17, yellow empty circles correspond to galaxies with global density 13 ≤ D8 < 17, blue crosses correspond to galaxies with global density 8 ≤ D8 < 13, and grey Xs denote galaxies with D8 < 8. Numbers are order numbers of groups with at least ten member galaxies from Table 2.
