Results are presented of investigations of rich clusters of galaxies from the Abell catalog with a distance class equal to or less than 3, based on observations at 102.5 MHz with the Pushchino phased antenna array. The radio luminosities and spectral indices of the clusters are determined, and the 102.5 MHz luminosity function of these clusters of galaxies is derived for the range 10 to the 25th to 10 to the 27th W/Hz. These findings are compared with optical and X-ray data, and the comparisons indicate correlations of the radio parameters (luminosity and spectral index) with the richness, morphological type, and X-ray luminosity of the clusters. It is shown that these statistical relations can be qualitatively explained by the influence of the hot intracluster gas on the evolution of active member radio galaxies.
