262144/177147
| Interval information |
reduced subharmonic
262144/177147, the Pythagorean diminished sixth, is a 3-limit interval. It is often called a "wolf fifth" due to appearing in the circle of fifths in Pythagorean 12-note tuning. It is separated from the classical wolf fifth 40/27 by a schisma. It is very closely approximated by 23edo's flat fifth of 13\23.
Temperaments
In compton temperament, this interval and 3/2 are tempered together, because the Pythagorean comma (531441/524288) is tempered out.
If this interval itself is taken as a comma to be tempered out, it leads to the malicious temperament, and the interval can be called the malicious comma (the origin of the "malicious compliance" pun from that page).
