Four Small Transiting-planet Candidate Signals around TOI-4405, TIC 101653309 and TIC 262843927 from TESS

I report four small transiting-planet candidate signals on three K and M dwarfs observed by TESS. Each was detected by box least squares and passes light-curve consistency tests; all were also vetted with difference-image localization and TRICERATOPS. As an additional check, each reappears in TESS sectors that its detection search did not use, at an ephemeris fixed beforehand. They are a 3.601-day, 1.35 R⊕ third signal around the K6 dwarf TOI-4405 (false-positive probability 0.014 with a digitized speckle contrast curve, 0.045 without); a 0.703-day, 1.30 R⊕ signal around the early-M dwarf TIC 101653309 at 60 pc; and 24.11-day (2.1 R⊕) and 14.52-day (1.9 R⊕) signals around the early-M dwarf TIC 262843927. All four appear in Eumemic's public search tables; the 14.52-day signal is his follow-up candidate. None is validated. TESS will not observe these stars through Sector 134, so I give predicted transit times for ground-based follow-up.
