superset of 125 and 50
"7\10" is clearer than "0.7 octaves". Harmonics -> subgroup. Add the missing 2 in 2.11.13. Resolve edo vs et

250edo is [[enfactoring|enfactored]] in the 7-limit, with the same tuning as 125edo, but provides a closer approximation to the harmonics 11 and 13. Being a small multiple of [[10edo]], it equates 13/8 with 0.7 octaves. Even so, there are a number of mappings to be considered, in particular, a less flat-tending [[patent val]] {{val| 250 396 580 '''702''' '''865''' '''925''' … }} and a more flat-tending 250deff… val {{val| 250 396 580 '''701''' '''864''' '''924''' … }}.

In addition, in the patent val in the 11-limit, it is a tuning for the [[Minortonic family#Seminar|seminar]] temperament.

Since 2.3.5.7 harmonics in the patent val 250edo come from 125edo, and 11.13 harmonics in the patent val come from 50edo, this system is worthy of being considered as a superset of these two temperaments.

Since the 2.3.5.7 subgroup in the patent val comes from 125et, and the 2.11.13 subgroup in the patent val comes from 50et, this system is worthy of being considered as a superset of these two temperaments.
