Abstract A search for close companion galaxies in a redshift-limited sample of Seyfert galaxies is reported. It is found that there is a definite excess of companions in that sample, compared with a control sample of field galaxies. The calculated percentage of Seyferts with physical companions is about 15 percent, while the upper limit on the percentage of the control-sample galaxies with physical companions is only 3.1 percent. Furthermore, about 7.5 percent of the Seyferts have companions that are very close and of comparable size, compared with only about 1 percent of the control sample.
