Redshift measures at 21 cm wavelength have been made on over 100 galaxies in more than 40 different groups with the Arecibo radio telescope. These groups generally consist of a large spiral galaxy with one or more companions. This list of galaxies is supplemented with over 160 galaxies in more than 40 groups with a dominant galaxy that is brighter than 11.8 mag. It is shown that the companion galaxies in these groups have significantly higher redshifts than the brightest galaxy in the group. The most accurate redshifts available in the Local Group (M31) and in the M81 group are analyzed. It is shown that all 21 of the best-known physical companions have significantly higher redshifts than the central galaxies. It is suggested that these companions contain a component of nonvelocity redshift. A detailed analysis of the tendency toward quantization in the differential redshift between the dominant galaxy and its companions is also presented.
