The following table lists EDFs up to 31 (and corresponding EDOs up to 53) that have arto and tendo thirds (which are defined broadly as a latitude of 22.5 to 30 degrees, which is moderately extended from the "canonical" arto and tendo latitude range of 24 to 28 degrees).

|Widest range; corresponds to slendric. Diatonic thirds in multiples of 5edo. Same intervals are shared with multiples of 3edf up to 21, so they are grouped here. 5edo fendo. (8edo's thirds aren't here cuz they're technically neogothic!)
