91st-octave temperaments occur naturally through an edo join between any two equal divisions whose greatest common divisor is 91. | |||
Of multiples of 91, [[364edo]] and [[1547edo]] are notable for having high consistency limits. Therefore protactinium, is considered below. | |||
Protactinium is described as the 364 & 1547 temperament and named after the 91st element. | == Protactinium == | ||
Protactinium is described as the 364 & 1547 temperament and named after the 91st element. Despite being consistent only up to 11-limit, [[1911edo]] is also a strong tuning. | |||
Coincidentally, it reaches [[91/64]] in 1 generator. | |||
