The 7/25·11 medium diesis is a comma with a ratio of 567/550 and a value of approximately 52.70 cents. In the Sagittal system, the downward version of this comma (possibly tempered) is represented (in a secondary role) by the 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 ⁠. The primary role of is 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 . The use of this comma for notation is extremely rare.
