| Interval information |
532400/531441, the tetracot schisma, is an unnoticeable 11-limit comma that splits the ptolemisma into two rastmas and equates a stack of two syntonic commas with 1331/1296, the Alpharabian parachromatic semilimma. In addition, it can be identified as the interval separating an octave-reduced stack of two 729/484 Alphrabian wide fifths from a 25/22 ptolemismic whole tone, and, it is the sum of the wizardharry comma and the parimo.
Etymology
The tetracot schisma was named by XA Discord user Neutraldown, because it is in the schisma size range and is tempered out by tetracot temperament. This deliberately parallels the name of the tetracot kleisma.
Previously it was named "anthill comma" after PLoS Biol. 2014 Mar; 12(3): e1001805. (the paper The Ecology of Collective Behavior by Deborah M. Gordon, about ant colonies), because 532400 / 531441 = ~1.001805. That name is no longer preferred, because "tetracot schisma" is more straightforward and informative.
