Abstract

Radio data (21 cm) on the redshifts of galaxies in small groups are analyzed for the previously reported 72 km s-1 quantization. The redshift differentials definitely clump about multiples of 72 km s-1, at a confidence level of 99.5%. The detailed deviations of the data from exact quantization are discussed in terms of the superposition of redshift states.
