Extensions
- Septichrome
- 13-limit semiseptichrome is questionable as it's much less accurate than the 11-limit, tho it is the central segment so idk.
- Slendscape
- 13-limit is questionable, but contrary to the case with semiseptichrome, this one is more complex. Perhaps it's okay to be (c.f. 13-limit trisedodge) but 15 & 270 deserves a catalog. I'm not fond of the name slendscape itself however cuz it's derived from slendroschisma.
- Avicenna
- The 17- and 19-limit versions (added by User: Gud2228 in 2022) are questionable. For example it's not supported by 357. Feels like an edge case so idk.
- Sextile
- The 17- and 19-limit versions (added by User: Gud2228 in 2022) are very questionable, perhaps should be replaced with no-17 19-limit. The 13-limit extension "sextilia" (12 & 270, also added by User: Gud2228 in 2022) looks useless; I think it can be safely deleted. If anything 12e & 270 deserves a catalog.
