405/392, the greenwoodma, is a 7-limit medium comma. Tempering it out, this leads to the greenwoodmic temperaments.
Sagittal notation
In the Sagittal system, the downward version of this comma (possibly tempered) is represented by the sagittal and is called the 49/5 medium diesis, or 49/5M for short, because the simplest interval it notates is 49/5 = 7×7/5 (equiv. 49/40), as for example in C-E . The upward version is called 5/49M or 49/5M up and is represented by .
