'''532400/531441''', the '''~~tetracot schisma~~''', is an [[unnoticeable comma|unnoticeable]] [[11-limit]] comma that splits the [[ptolemisma]] into two [[rastma]]s and equates a stack of two [[syntonic comma]]s 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]].

'''532400/531441''', the '''anthill comma''', is an [[unnoticeable comma|unnoticeable]] [[11-limit]] comma that splits the [[ptolemisma]] into two [[rastma]]s and equates a stack of two [[syntonic comma]]s with [[1331/1296]], the Alpharabian parachromatic semilimma.

== 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]]~~.

[[Budjarn Lambeth]] named the "anthill comma" after [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3949665/ PLoS Biol. 2014 Mar; 12(3): e1001805.] (''The Ecology of Collective Behavior'' by Deborah M. Gordon), a paper about ant colonies. This referenced the comma’s ratio: 532400 / 531441 = ~1.001805.

~~Previously it was named "anthill comma" after~~ [~~https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3949665/ 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~~.

XA [[Discord]] user Neutraldown also proposed the name "tetracot schisma" for this comma, because it is in the [[schisma]] size range and is [[tempered out]] by [[tetracot]] temperament. This deliberately parallels the name of the [[tetracot kleisma]].
