Tritonopod

Period-35, 17 generators are equal to 7/5, 18 generators are equal to 10/7.

Soviet Ferris wheel

Defined as the 320 & 460 temperament, and named because it's a period-20 temperament, and there are 20 cabins on a standard ferris wheel found throughout most of Eastern Europe and Central Asia (as in abandoned Pripyat wheel, for example).

17-limit

Subgroup: 2.3.5.7.11.13.17.19

Comma list: 833/832, 1001/1000, 1225/1224, 4225/4224, 4459/4455

Mapping generators: ~88/85, ~238/165

Optimal tuning (CTE): ~238/165 = 633.913

Vals: 140, 320, 460

19-limit

Subgroup: 2.3.5.7.11.13.17.19

Comma list: 833/832, 1001/1000, 1225/1224, 1729/1728, 2926/2925, 4459/4455

Mapping generators: ~88/85, ~238/165

Optimal tuning (CTE): ~238/165 = 633.913

Vals: 140, 320, 460

Calcium

A highly precise 2000 & 2460 temperament, named following the convention of naming some fractional-octave temperaments after chemical elements.

23-limit

Subgroup: 2.3.5.7.11.13.17.19.23

Comma list: 9801/9800, 10626/10625, 12376/12375, 21505/21504, 21736/21735, 89376/89375, 123201/123200

Mapping generators: ~88/85, ~11875/10752

Optimal tuning (CTE): ~11875/10752 = 172.196

Vals: 460, 2000, 2460

Playing cards

It is the 31-limit temperament defined as 2860 & 3224 by tempering out the 2.29.31 [-5 -52 52] comma, which sets a stack of 52 31/29s equal to 5 octaves.

Since it is conceived in the 31-limit, it makes no sense to define it for smaller subgroups.

Subgroup: 2.3.5.7.11.13.17.19.23.29.31

Optimal tuning (CTE): ~?

Binilnilium

Named after the provisional name for the 200th element, tempers out the 200-comma ([-317 200>) and the ragisma (4375/4374).

Nuclear matter

Defined as the 22 & 69 temperament, and the comma in the 5-limit is [-41, 1, 17⟩. The name comes from the fact that nuclear matter density is 4.1 * 10^17 kg/m^3.

Subgroup: 2.3.5

Comma list: [-41, 1, 17⟩

Optimal tuning (CTE): ~5/4

Vals: 22, 69

Berkelium

Named after the 97th element.

Subgroup: 2.3.5.7.11.13

Comma list: 4375/4374, 405769/405504, 1063348/1063125, ...

Mapping generators: ~144/143, ~3/2

Optimal tuning (CTE): ~3/2 = 701.945

EDOs: 388, 2619, ...

Point Zero Seven

A meantone version of sextilififths that's quite bad at JI. Named because the generator is 7\100, and since the name sounds like an alcohol percentage, it aligns with the badness of JI of the scale.

Subgroup: 2.3.5.7

Comma list: 81/80, 121500/117649

Mapping: [1 2 4 4], [0 -6 -24 -17]

Optimal tuning (CTE): ~21/20 = 83.888

Vals: 14, 43, 100
