3776edo is a | 3776edo is a good 2.3.11.13.19 subgroup system. It does not tune the [[15-odd-limit]] consistently, though a reasonable represenation exists through the 19-limit patent val. There, it provides the [[optimal patent val]] for the [[oganesson]] temperament in the 7-, 11-, 13-, 17-, and the 19-limit. It tempers out the [[quartisma]] in the 11-limit, and is a tuning for the rank-3 [[van gogh]] temperament. | ||
In the 19-limit, and 2.3.5.17.19 subgroup, 3776edo tempers out the comma that associates [[171/170]] to 1 step of 118edo, hence enabling usage of this interval as microchroma. This is strengthened by 3776edo's strong and consistent approximations of [[19/17]] and [[10/9]], intervals that are one 171/170 apart. | |||

Since 3776 factors as {{Factorization|3776}}, 3776edo has subset edos {{EDOs|2, 4, 8, 16, 32, 59, 64, 118, 236, 472, 944, 1888}}, of which [[16edo]], [[118edo]] and [[472edo]] are particularly notable. | |||
