Promethium splits the perfect fifth in two and can be described as the 183 & 2684 temperament. By tempering out 4100625/4100096 promethium identifies the diaschisma with [[2025/2002]] in the 13-limit and also in the 17-limit. | Promethium splits the perfect fifth in two and can be described as the 183 & 2684 temperament.
