Scientific paper

The power-law form of the two-point spatial correlation function of groups of galaxies is observed among a statistically homogeneous group sample based on the CfA redshift survey. The correlation range is from 5 to 40 Mpc (H0 = 100 km/sec Mpc). The power index is 1.8, and the correlation strength is 45, which is consistent with its dependence on the mean separation and richness of galaxy systems. This correlation of groups suggests the existence of the structure in the intermediate scale between galaxies and clusters of galaxies.
