ed16.67616¢

This segment is about the equal temperament of EPD16.67616cents.

This is about 71.959EDO, so it's simply an alternative tuning of 72edo. The comma basis, mappings, etc. show up as same as 72edo.

I use this for 2.3.5.7.11.17.19 subgroup.

72edo didn't work well with 2.3.7.11.13 subgroup because it can't deal with the Harmonisma, and map it to 1 step.

This segment is about the equal temperament of EPD38.8154cents.

This is about 30.92EDO, so it's simply an alternative tuning of 31edo. The comma basis, mappings, etc. show up as same as 31edo.

I use this for 2.3.5.7.11 subgroup.

This segment is about the equal temperament of EPD20.71628cents.

This is about 57.925EDO, so it's simply an alternative tuning of 58edo. The comma basis, mappings, etc. show up as same as 58edo.

I use this for 2.3.5.7.11.13 subgroup.

This is a hamormonismic, minor minthmic. A rastmic, and a major minthmic, which ends up it's also a grossmic.
