Quartismic family
The quartismic family is built up from temperaments that temper out the quartisma- the unnoticeable comma with the ratio 117440512/117406179, and a monzo of [24 -6 0 1 -5⟩- and among the members of this family are Altierran, Meanquarter, Coin, Kleirtismic, and Doublefour. Despite that fact that the quartisma is an unnoticeable comma in JI, a number of reasonably well known EDOs (such as 17edo, 26edo and 34edo) actually fail to temper it out, rendering them unsuitable for temperaments in this family. In fact, there are even some EDOs such as 23edo and 70edo that seem to temper out the comma when one merely examines the patent vals, yet, upon closer examination, actually fail to temper out the comma as these calculations prove, and are thus unsuitable for temperaments in this family. Examples of edos that actually do temper out the quartisma are 22edo, 24edo, 46edo, 68edo, 159edo, 224edo and 3125edo.
Quartismic
The 11-limit parent comma for the quartismic family is the the quartisma with a ratio of 117440512/117406179 and a monzo of [24 -6 0 1 -5⟩. As the quartisma is an unnoticeable comma, this rank-4 temperament is a microtemperament.

5-limit Representation
Among quartismic temperaments, there are several options for 5-limit representation depending which among the various 5-limit commas is tempered out. Adding the schisma to the list of tempered-out commas results in some form of Altierran temperament. Adding the meantone comma results in some form of Meanquarter temperament. Adding the magic comma results in some form of Coin temperament. Adding the kleisma results in some form of Kleirtismic temperament- the "kleir-" in "Kleirtismic" is pronounced the same as "Clair". Adding the tetracot comma results in some form of Doublefour temperament. Other possible extensions are listed here.
