is it worth mentioning that 147edo tempers out 3489660928/3486784401 in the 2.3.13 subgroup? in the way of technical data, there's nothing in the section about its 2.3.13.23 subgroup that isn't also true of shoal. Squib (talk) 15:25, 1 March 2026 (UTC)

- It equates 16/13 with (256/243)4. Apparently it's tempered out by 53edo too (which also has a strong 2.3.13) so should it get its own page? Squib (talk) 05:34, 2 March 2026 (UTC)
- This comma has a name already, called tridecapyth comma. It simply maps prime 13 to twenty perfect fifths, and cassandra, which 147et supports, tempers it out. —FloraC (talk) 13:17, 2 March 2026 (UTC)
