Theory

4349edo is a fairly strong 29-limit system, consistent to the 29-odd-limit. We may note it is a counterquectismic, fortune, and euzenius system. Some of the simpler commas in tempers out in the higher limits include 151263/151250 and 1771561/1771470 in the 11-limit; 123201/123200 in the 13-limit; 12376/12375 in the 17-limit; 10241/10240, 13377/13376, 89376/89375 in the 19-limit; 12168/12167, 25025/25024, 76545/76544 in the 23-limit; 47125/47124 and 25840/25839. Since it tempers out 12168/12167, it allows vicetertismic chords in the 23-odd-limit.
