| '''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. 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 '''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.

| 532400 / 531441 = ~1.001805. The comma is named after [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3949665/ PLoS Biol. 2014 Mar; 12(3): e1001805.], which is the paper ''The Ecology of Collective Behavior'' by Deborah M. Gordon. The paper discusses the emergent top-down and bottom-up behaviour of systems containing a number of individual organisms, and extensively discusses how the behaviour of the ant emerges from the anthill, yet the behaviour of the anthill emerges from the ant, in a kind of self-sustaining loop.
| | 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]]. |

| After [[Budjarn Lambeth]] coined this name, the name was called out on the XA Discord for its convoluted etymology. Many people in the Discord suggested that names like these which convey no information about a comma’s properties are more hindrance than help to musicians and theorists, and that commas would be better off being referred to by just their [[ratio]] or [[monzo]] instead of by such confusing names. In response to the criticism, Lambeth decided to retract almost all of his comma names, including this one, due to their arbitrary and confusing nature. However, one Discord user remarked that there was actually something oddly fitting about “anthill” for this comma, and that it would be a shame to see this name go. So, the other commas' names were retracted, but “anthill comma” was kept.
| | 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. |
