-By also tempering the semitonisma ([[289/288]]), an efficient temperament known as [[Srutal archagall]] is achieved, which is equivalently described as [[charic]] [[semitonic]].
-This is because of a general fact of [[S-expression]]s; in this case it manifests as that: {[[diaschisma|S16<sup>2</sup> × S17]] , [[24576/24565|S16/S17]]} = {[[256/255|S16]], [[289/288|S17]]}
