Sagittal notation
In the Sagittal system, the downward version of this comma (possibly tempered) is represented by the sagittal and is called the 25 small diesis, or 25S for short, because the simplest interval it notates is 25/1 = 5×5 (equiv. 25/16), as for example in E -B . The upward version is called 1/25S or 25S up and is represented by .
