The Zwicky cluster Zw 1122.3+6317, which contains four Markarian galaxies, is discussed. Radial velocities are determined for three galaxies in the region of the sky occupied by this cluster. It is shown that the cluster is very open and consists mainly of spirals, that some compact ellipticals are possible cluster members, and that the Markarian galaxies are among the brightest cluster members. Spatial and kinematic characteristics of the cluster are estimated, including a mean recession velocity of 3557 km/s, a radial-velocity dispersion of 219 km/s, a virial mass of 92 trillion solar masses, a crossing time of 2.9 billion years, a luminosity of 1.1 trillion suns, and an M/L ratio of 84 (in solar units). The possibility is noted that this cluster might actually be two groups of galaxies, with mean recession velocities of approximately 3350 and 3750 km/s, projected onto each other.
