However, our spectroscopy shows it to be at a relatively modest redshift of z = 0.917. Its spectrum is dominated by a red stellar continuum and strong [O II] emission. The infrared magnitude of 3C 364 is K = 17.27, typical for 3CR and 1 Jy-class radio galaxies at z ~ 0.9. Its radio luminosity [log_10_P_1.4GHZ, rest_(W Hz^-1^) = 27.71] is much smaller than the distant 4C radio galaxies with comparably steep radio spectra. We emphasize that AGN radio properties correlate with optical/IR luminosity and redshift only in a statistical manner.
