The '''frostma'''  ([[ratio]]: 245/242, [[monzo]]: {{monzo| -1 0 1 2 -2 }}) is a [[small comma|small]] [[11-limit]] [[comma]] named after [[User:Frostburn|Frostburn]] used in the construction of the [[No-threes subgroup temperaments #Frostburn|frostburn]] temperament.
The '''frostma'''  ([[ratio]]: 245/242, [[monzo]]: {{monzo| -1 0 1 2 -2 }}) is a [[small comma|small]] [[11-limit]] [[comma]] used in the construction of the [[No-threes subgroup temperaments #Frostburn|frostburn]] temperament.


It can be factored into ([[243/242]])([[245/243]]).  
It can be factored into ([[243/242]])([[245/243]]) and ([[896/891]])([[2835/2816]]).


When tempered out, it equates a stack of two [[11/7]]<nowiki/>s with a [[5/2]] major tenth.  
== Temperaments ==
Tempering out this comma alone in the 11-limit results in the rank-4 '''frostmic temperament''' (→ [[Catalog of rank-4 temperaments #Frostmic (245/242)]]), where a stack of two [[11/7]]'s is equated with a [[5/2]] major tenth, enabling [[frostmic chords]].  


== History ==
== Etymology ==
Before the comma got the name ''frostma'', it was known as the ''cassacot'', probably derived from [[cassandra]] and [[tetracot]]. However, ''cassandra'' was a misnomer for [[andromeda]]. The temperament's name was later corrected. Since then, ''cassacot'' has lost its root, thus justifying the new name.
