Transit-timing variations of TOI-6041b with a hypothetical planet placed between planets b and c. We adopt circular and coplanar orbits for all three planets and consider two orbital periods for the additional planet: 36 d (blue) and 41 d (red), corresponding to potential 4:3 and 3:2 MMRs with planet b. In both cases, the resulting TTV amplitudes are consistent with the observed variations.
