2048/2025, the diaschisma, an interval of 19.553 [[cent|cents]], it is the difference between four perfect fifths plus two major thirds and three octaves, Tempering it out leads to [[Diaschismic family|Diaschismic temperament]]. It may also be defined as the difference between a just Pythagorean minor seventh and a just augmented sixth (E.A. [[16_9|16/9]] - 225/128), as the difference between two [[16_15|diatonic semitones]] and the [[9_8|major whole tone]], that is, (9/8)/(16/15)^2, or as the difference between the 5-limit tritones, [[45_32|45/32]] and its enharmonic equivalent [[64_45|64/45]].
