We present our second catalog of quadruple star candidates, containing 101systems discovered in TESS Full-Frame Image data. The targets were initiallydetected as eclipsing binary stars with the help of supervised machine learningmethods applied to sectors Sectors 1 through 54. A dedicated team of citizenscientists subsequently identified through visual inspection two sets ofeclipses following two different periods. All 101 systems presented here passcomprehensive photocenter motion tests confirming that both sets of eclipsesoriginate from the target star. Some of the systems exhibit prominent eclipsetime variations suggesting dynamical interactions between the two componentbinary stars. One target is an eclipsing quintuple candidate with a (2+1)+2hierarchical configuration, such that the (2+1) subsystem produces eclipses onthe triple orbit as well. Another has recently been confirmed as the secondshortest period quadruple reported to date. This catalog provides ephemerides,eclipse depths and durations, sample statistics, and highlights potentiallyinteresting targets for future studies.
