The distribution of a subsample of galaxies from the CfA survey is examined by means of the percolation method to draw conclusions about large-scale galactic structures, with attention given to luminosities. Volume-limited subsamples are taken from the CfA survey, analyzed by percolation, and compared with each other by means of Monte Carlo sampling. Heirarchical clustering is noted for the most luminous galaxies, whereas stringlike or sheetlike distributions characterize the least luminous galaxies. The results indicate that the large-scale distributions of galaxies with different luminosities are different. The large-scale distribution is found to be consistent with previous fractal and two-point correlation analyses. The results are applicable to the study of some aspects of the unified description of the large-scale structure of the universe and the mechanism of galaxy formation.
