The high-redshift radio-loud quasar PKS 2126-158 is found to have a large number of red galaxies in close apparent proximity.We use the Gemini Multi-Object Spectrograph (GMOS) on Gemini South to obtain optical spectra for a large fraction of these sources. We show that there is a group of galaxies at z 0.66, coincident with a metal-line absorption system seen in the quasar s optical spectrum. ... All confirmed members exhibit early-type galaxy spectra, a rare situation for a MgII absorbing system. ...
