The frostma (ratio: 245/242, monzo: [-1 0 1 2 -2) is a small 11-limit comma named after Frostburn used in the construction of the frostburn temperament.

It can be factored into (243/242)(245/243).

History

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.
