'''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 '''anthill comma''', is an [[unnoticeable comma|unnoticeable]] [[11-limit]] comma that splits the [[ptolemisma]] into two [[rastma]]s, equates a stack of three instances of [[88/81]] with [[32/25]], and equates a stack of two [[syntonic comma]]s with [[1331/1296]], the Alpharabian parachromatic semilimma.

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]]. | 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.
