250edo is 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 ⟨250 396 580 702 865 925 …] and a more flat-tending 250deff… val ⟨250 396 580 701 864 924 …].
In addition, in the patent val in the 11-limit, it is a tuning for the seminar temperament.
Divisors
250edo has subset edos 1, 2, 5, 10, 25, 50, 125.
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.
