== Theory ==
1778edo is [[consistent]] to the [[9-odd-limit]], but the errors of both [[harmonic]]s [[5/1|5]] and [[7/1|7]] are quite large. It is [[enfactoring|enfactored]] in the 5-limit, with the same tuning as [[889edo]], [[tempering out|tempering out]] {{monzo| -29 -11 20 }} (gammic comma) and {{monzo| -69 45 -1 }} ([[counterschisma]]). In the 7-limit, the equal temperament tempers out 2401/2400 ([[breedsma]]) and 48828125/48771072 (neptunisma). It provides the [[optimal patent val]] for the 7-limit [[neptune]] temperament.
 
For higher harmonics, it is suitable for a 2.3.11.19.23.43.47.61 [[subgroup]] interpretation.
 
=== Odd harmonics ===
{{Harmonics in equal|1778}}
{{Harmonics in equal|1778}}
Prime harmonics with less than 1 standard deviation in 1778edo are: 2, 3, 11, 23, 43, 47, 61. As such, it is best for use with the 2.3.11.23.43.47.61 subgroup.


In the 7-limit, it provides the optimal patent val for the [[neptune]] temperament.
=== Subsets and supersets ===
Since 1778 factors into {{factorization|1778}}, 1778edo has subset edos {{EDOs| 2, 7, 14, 127, 254, and 889 }}.
