22nd-octave temperaments

22edo is a notable tuning system, and as such it gives rise to some fractional-octave temperaments.

Icosidillic

Major Arcana

Named after a subset of Tarot cards of which there is 22. Tempers out the [-193 154 -22⟩ comma in the 5-limit. Can be conceptualized as a more precise version of icosidillic in the 5-limit and the 7-limit, however there's no single way to extend it to the 11-limit due to inconsistency.

Subgroup: 2.3.5

Comma list: [-193 154 -22⟩

Mapping: [⟨22 22 -39], ⟨0 1 7]]

Mapping generators: ~[79 -63 9⟩, ~3/2

Optimal tuning (CTE): ~3/2 = 701.942

Vals: Template:Val list, ...

7-limit
