The squbema, 729/728, is a 13-limit superparticular comma measuring about 2.4 ¢. It often arises as the difference between simpler commas: (225/224)/(325/324), (243/242)/(364/363), (351/350)/(676/675), (540/539)/(2080/2079). It factors into (1575/1573)(9801/9800) as well as (2200/2197)(123201/123200).
Tempering out this comma in the 13-limit leads to the rank-5 squbemic temperament, and enables squbemic chords. It is tempered out by several notable edos including 41edo, 72edo and 313edo among others, as well as by the 13-limit amity temperament.
