We thank J. Kriesslar and T. Beers for providing the galaxy number density plot of Abell 754 and Jonathan Schachter for useful discussions. Also, we are indebted to J. Huchra, P. Berlind, J. Mader, S. Tokarz and D. Fabricant for the help in obtaining and analyzing an optical spectrum of the galaxy based on observations made with the Multiple Mirror Telescope, a joint facility of the Smithsonian Institution and the University of Arizona.

MERLIN is a UK national facility, operated by the University of Manchester on behalf of the Particle Physics and Astronomy Research Council. We thank S. Garrington for calibrating our data.
