The quartisma or Saquinlu-azo comma is an 11-limit comma with a ratio of 117440512/117406179 and a monzo of [24 -6 0 1 -5⟩. It has a value of approximately 0.50619 cents- meaning it is an unnoticeable comma- and it is the difference between a stack of five 33/32 quartertones and one 7/6 subminor third. Examples of edos that temper out the quartisma are 22edo, 23edo, 24edo, 46edo and 159edo.
The rank-3 quartismic or Saquinlu-azo temperament is the rank-3 2.3.7.11 temperament that tempers out this comma; equivalently it is the 22&24&159 temperament. This page will also list various rank-2 temperaments that temper out this comma and thus belong in the quartismic family.
