532400/531441, the anthill comma, 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

532400 / 531441 = ~1.001805. The comma is named after 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.
