'''4375/4374''', the '''ragisma''', being the difference between a stack of two [[27/25|large limmas]] and [[7/6]], is a [[7-limit]] [[unnoticeable comma]]. It is the smallest 7-limit [[superparticular]] ratio. It is tempered out in [[ragismic microtemperaments]]. 4375/4374 is also equal to ([[25/18]])2/([[27/14]]) and the difference between a [[kleisma]] (S252 * S26) and a [[marvel comma]] (S15 = S25 * S26 * S27), hence its expression as S25 / S27 which directly implies it can be expressed as (28/24 = [[7/6]])/([[27/25]])2.
