Abstract: | By cluster analysis, we study the clustering properties of Luminous Red Galaxies (LRGs) and compare them with those of Main galaxies. We find that the clustering properties of Luminous Red Galaxies is different from those of Main galaxies, and that LRGs cluster mainly in form of close double and multiple galaxies, galaxy groups.
