7L 4s's generator range contains [[17/14]] and [[23/19]].
7L 4s's generator range contains [[17/14]] and [[23/19]].


In the equal divisions which are in the size of hundreds, [[cohemimabila]] temperament is the first intepretation of 7L 4s of reasonable hardness (roughly semihard) through regular temperament theory. It is supported by [[43edo]], notable for being studied by [[Wikipedia:Joseph Sauveur|Joseph Sauveur]] due to harmonic strength, and [[111edo]], which is uniquely consistent in the 15-odd-limit. The generator is mapped to [[128/105]], and in higher limits it is tempered together with 17/14. While not typical of regular temperament theory, the scale can be made by using every other generator of the [[tertiaseptal]] temperament, for example in [[159edo]].
