| '''6250/6237''', the '''liganellus comma''', otherwise known as the '''liganellisma''', or – in the earliest materials where this comma is named – the '''liganelluma''', is a [[small comma|small]] [[11-limit]] comma with a value of roughly 3.6 [[cent]]s. It is the difference between [[100/99|100/99 (ptolemisma)]] and [[126/125|126/125 (septimal semicomma)]], and between the [[symbiotic comma]] and the [[amity comma]]. In addition, it is the sum of [[3025/3024|3025/3024 (lehmerisma)]] and [[4000/3993|4000/3993 (wizardharry comma)]]. The liganellus comma is also the interval that separates the [[385/384|keenanisma]] from the [[kleisma]] on one side, and from the undecimal hemifourths comma on the other. When this comma is tempered out, [[80/77]] – the difference between [[5/4]] and [[77/64]] – is equated with the major diesis of [[648/625]]. Although this comma is more commonly tempered out as a byproduct of tempering out other commas, those temperaments in which this comma is tempered out in a linearly independent fashion are called "[[liganellus temperaments]]".

It factors into simpler commas as ([[3025/3024]])⋅([[4000/3993]]). |

| The term "liganellus", from which this comma's names are derived, is a portmanteau of Latin ''ligare'' (to ''tie'', to ''bind''<ref>[[Wiktionary: ligo #Latin]]</ref>) and Latin ''anellus'' (refering to a little ring<ref>[[Wiktionary: anellus #Latin]]</ref>, including the sort which forms an element in a chain) that was coined in reference to the fact that 6250/6237 is tempered out in [[Ragismic microtemperaments #Octoid|octoid]], [[Kleismic family #Tritikleismic|tritiklesmic]], [[Kleismic family #Catakleismic|catakleismic]], [[Kleismic family #Quadritikleismic|quadritikleismic]], [[Pythagorean family#Compton temperament|compton]], [[Breedsmic temperaments #Unthirds|unthirds]], [[Amity family|amity]], [[Hemifamity temperaments #Alphaquarter|alphaquarter]], [[Lehmerismic temperaments #Hanuman|hanuman]], and [[Kleismic rank three family #Enlil|enlil]] (thus linking all of these temperaments together, hence Latin "ligare"), as well as to its aforementioned relationship with the keenanisma where it forms the "links" that make up the aforementioned chain (hence Latin "anellus").
| | == Temperaments == |
| | [[Tempering out]] this comma leads to the rank-4 '''liganellus''' temperament, in which [[80/77]] – the difference between [[5/4]] and [[77/64]] – is equated with the major diesis of [[648/625]]. It is commonly tempered out as a byproduct of tempering out other commas. |

| * [[Small comma]]
| | This comma was named by [[Aura]] in 2020. In the earliest materials where this comma is named, it was known as the ''liganelluma''. The term ''liganellus'', from which this comma's names are derived, is a portmanteau of Latin ''ligare'' ("to tie", "to bind"<ref>[[Wiktionary: ligo #Latin]]</ref>) and Latin ''anellus'' (referring to a little ring<ref>[[Wiktionary: anellus #Latin]]</ref>, including the sort which forms an element in a chain) that was coined in reference to the fact that 6250/6237 is tempered out in [[octoid]], [[tritikleismic]], [[catakleismic]], [[quadritikleismic]], [[compton]], [[unthirds]], [[amity]], [[alphaquarter]], [[hanuman]], and [[enlil]] (thus linking all of these temperaments together, hence Latin ''ligare''), as well as to its aforementioned relationship with the keenanisma where it forms the "links" that make up the aforementioned chain (hence Latin ''anellus''). |
