Theory

410edo is enfactored in the 5-limit, with the same tuning as 205edo characterized by tempering out 1600000/1594323 (amity comma) and [38 -2 -15⟩ (luna/hemithirds comma), as well as [-29 -11 20⟩ (gammic comma) and [47 -15 -10⟩ (quintosec comma), but the approximations to harmonics 7 and 13 are much improved. The equal temperament tempers out 2401/2400 (breedsma), 4802000/4782969 (canousma), and 48828125/48771072 (neptunisma) in the 7-limit; 5632/5625, 9801/9800, 14641/14580, and 117649/117612 in the 11-limit; 676/675, 1001/1000, 1716/1715, 2080/2079, 4096/4095, and 4225/4224 in the 13-limit.

410edo provides the optimal patent val for the 11- and 13-limit semiluna, hemiluna, and floral temperaments, the rank-3 semicanou temperament, and the rank-4 temperament tempering out 14641/14580.

410edo works much better as a no-11 no-13 subgroup temperament, with a sharp tendency to harmonics up to 29. For example, it tempers out 1216/1215, 1225/1224, 1445/1444, and 2500/2499 in the 2.3.5.7.17.19 subgroup.

Subsets and supersets

Since 410 factors into 2 × 5 × 41, 410edo has subset edos 2, 5, 10, 41, 82, and 205. Meanwhile, as every sixth step of 2460edo, a step of 410edo is exactly 6 minas.

As such, it supports edfs which are divisors of 240. In addition, its perfect fourth is on the 170th step, which while is not highly composite, is still notable to carry a few ed4/3 scales. This can be used to play Kartvelian scales.
