9L 2s is a MOS generated by an approximate 15/11 of 4\9edo (533.333 cents) to 5\11edo (545.4545). It represents temperaments like Avila (narrow generator) and Casablanca (wide). There is no TAMNAMS name for this MOS, but CompactStar suggested the names ultradiatonic and superarmotonic by analogy to 7L 2s's name of superdiatonic.
