[[1617/1600]] is the amount by which [[11/10]] exceeds [[160/147]].
The '''antimisma''', '''1617/1600''', is an [[11-limit]] [[small comma]]. It is the amount by which [[11/10]] exceeds [[160/147]]. It is also the difference between the ptolemisma ([[100/99]]) and the septimal diesis ([[49/48]]), making it an anti-ptolemisma, or anti-misma. However, that is not the origin of the name. In fact, it is named after [[Wikipedia: Antimo Liberati|Antimo Liberati]], because his birth year of 1617 is the numerator of this comma.

A stack of two septimal tritones ([[7/5]]) and an undecimal superfourth ([[11/8]]) is an antimisma above a perfect eleventh ([[8/3]]). While this leads to an essentially tempered chord of 1/1-7/5-49/25-8/3, it's rather far-flung.

The antimisma, 1617/1600, is an 11-limit small comma. It is the amount by which 11/10 exceeds 160/147. It is also the difference between the ptolemisma (100/99) and the septimal diesis (49/48), making it an anti-ptolemisma, or anti-misma. However, that is not the origin of the name. In fact, it is named after Antimo Liberati, because his birth year of 1617 is the numerator of this comma.

A stack of two septimal tritones (7/5) and an undecimal superfourth (11/8) is an antimisma above a perfect eleventh (8/3). While this leads to an essentially tempered chord of 1/1-7/5-49/25-8/3, it's rather far-flung.
