-The '''7/25·11 medium diesis''' is a comma with a ratio of 567/550 and a value of approximately 52.70 [[cent]]s. <span id="Sagittal notation"></span>In the [[Sagittal]] system, the downward version of this comma (possibly tempered) is represented (in a secondary role) by the sagittal {{sagittal | \!/ }} and is called the '''25·11/7 medium diesis''', or '''25·11/7M''' for short, because the simplest interval it notates is 25×11/7 = 5×5×11/7 (equiv. 275/224), as for example in C-E{{nbhsp}}{{sagittal | \!/ }}. The primary role of {{ sagittal | \!/ }} is [[33/32#Sagittal notation | 32/33]] (11M down). The upward version is called '''7/(25·11)M''' or '''25·11/7 up''' and is represented (in a secondary role) by {{sagittal| /|\ }}. The use of this comma for notation is extremely rare.
