262144/253125, the passion comma, is a 5-limit comma measuring about 60.6 cents. It is the amount by which five 16/15 exceed 4/3. Tempering out this comma in the 5-limit results in the passion temperament, which generates a quasidozenal (12L 1s) MOS, essentially a compressed 12edo scale if you ignore the octave. In addition to 12edo itself, passion is less accurately supported by several small EDOs of the form 12n+1 such as 25edo, 37edo, and 49edo (all containing superpyth/archy-style fifths).
