Galaxy mergers are a mechanism for rapid quenching of star formation. We are studying E+A galaxies (a type of post-starburst galaxy) and how they are impacted by merging. Examining E+A galaxies with companions offers insight into the evolution of E+As and the quenching process. The Y/Dim Collaboration collected a sample of E+A candidate galaxies from the SDSS DR16. Among the E+A candidates that were visually identified as interacting, 14 were spectroscopically confirmed to have companions. Our sample contained 11 pairs of galaxies and two groups of three galaxies. In one of these groups of three, there are two E+A candidates. Nine of these E+A candidates are involved in minor interactions with their companions.
