49/45

49/45 is a 7-limit interval. It appears as the interval between 15/14 and 7/6 as well as 9/7 and 7/5, and their inversions. It therefore functions as a diminished third, flat of the Pythagorean diminished third by a septimal comma and an aberschisma. Alternatively, if viewed as a second, it is flat of the whole tone by 405/392, the greenwoodma.
