The data on galaxy clustering is summarized, and the results of n-body simulations for understanding the large-scale structure of the Universe are briefly discussed. Evidence for the missing mass is stated, including studies of red-shift data for isolated binary galaxies, applications of the virial theorem to groups of galaxies, pair-weighted analysis of the velocity field, and the Virgo infall test. Several very strong constraints on cosmogonic scenarios are suggested, including the predominantly nonbaryonic makeup of the Universe and the importance of nongravitational, dissipative effects in separating the dark halo from the luminous galaxies.
