Theory
367et is only consistent to the 5-odd-limit, with three mappings possible for the 7-limit:
- ⟨367 582 852 1030] (patent val)
- ⟨367 582 852 1031] (367d val)
- ⟨367 582 853 1031] (367cd val)
Using the patent val, it tempers out 15625/15552 and [102 -57 -5⟩ in the 5-limit; 5120/5103 and 40353607/39858075 in the 7-limit.
Using the 367d val, it tempers out 15625/15552 and [102 -57 -5⟩ in the 5-limit; 2460375/2458624 and 2097152/2083725 in the 7-limit.
Using the 367cd val, it tempers out 268435456/263671875 and [33 -34 9⟩ in the 5-limit; 5120/5103, 7558272/7503125 and 235298/234375 in the 7-limit.
