== Theory ==

1665edo is a very strong 5-limit (as well as 2.3.5.11 [[subgroup]]) tuning and it is [[consistent]] in the [[15-odd-limit]]. In the 5-limit, 1665edo is a tuning for the [[gross]] temperament.

~~1665cc~~ val ~~is a tuning~~ for the [[~~roentgenium~~]] temperament, ~~and~~ the patent val ~~tunes the unnamed 111 & 1665~~ temperament in the 13-limit ~~which has a comma basis {6656/6655, 123201/123200, 250047/250000, 91182091/91125000}~~.

1665edo provides the [[optimal patent val]] for the [[rhodium]] temperament in the 11-limit and also in the 13-limit. In addition, it provides the optimal patent val for [[dzelic]] temperament in the 13-limit.

==Regular temperament properties==

The 1665cc val is a tuning for the [[roentgenium]] temperament, and the patent val tunes the unnamed 111 & 1665 temperament in the 13-limit which has a comma basis {6656/6655, 123201/123200, 250047/250000, 91182091/91125000}.

=== Subsets and supersets ===

Since 1665 factors into {{factorization|1665}}, 1665edo has subset edos {{EDOs| 3, 5, 9, 15, 37, 45, 111, 185, 333, and 555 }}.
