10/9, 15/14 (7-limit)
7-odd-limit: 161.4 ¢
7-odd-limit: 5 notes
Antonian is an exotemperament that tempers out 10/9, the classic major second. This equates 3/2 with 5/3, 4/3 with 6/5, and 5/4 with 9/8, being even less accurate than more common archetypal exotemperaments like father or dicot. It can be represented by only 3edo in its patent val.
In septimal antonian, 7/6 is equated to 5/4 and 9/8, by tempering out 15/14 and 28/27. An alternative extension is phlegyas, which tempers out 35/32 and 64/63, so 8/7 is equated with 5/4 and 9/8 instead.
