uniwizma
The uniwiz comma (monzo: [-11 -6 4 4⟩, ratio: 1500625/1492992), is the small interval that separates a stack of four 35/24 subfifths with the just major ninth 9/2. It also is the difference between 9/8 and a stack of four 36/35 quartertones.
Approximations
It is very well approximated by 1\145 and 2\270, and consistently represented in edos such as 171, 224, and 441.
Temperaments
When tempered out alone, it leads to the 7-limit version of the rank-3 uniwiz temperament, which has ~36/35 (or ~35/24) and ~5/4 as generators, and a semi-octave period. This has the effect of splitting the whole tone in four equal parts. Because it has 2 periods per octave, odd-numbered edos cannot be tempering out this comma.
When the schisma is added, it leads to the rank-2 kleischismic, for which 94 and 118 are great edos. Despite the name kleischismic, it does not temper out the kleisma. It finds ~3/2 at 2 generators plus a semioctave. By tempering out 1225/1224, it also finds ~17/16 at two generators.
