'''4096/4095''', the '''minisma''' or '''minic comma''', also described as the ''tridecimal schisma'' or ''tridecimal schismina''<ref>[https://sagittal.org/sagittal.pdf Sagittal – A Microtonal Notation System] by [[George Secor|George D. Secor]] and [[Dave Keenan|David C. Keenan]]</ref>, is an [[unnoticeable comma|unnoticeable]] [[13-limit]] [[superparticular]] [[comma]] of about 0.42 cents. It is the difference between the [[64/63|septimal comma (64/63)]] and the [[65/64|wilsorma (65/64)]], and between the [[36/35|septimal quartertone (36/35)]] and the [[1053/1024|tridecimal quartertone (1053/1024)]]. It is also a [[Mersenne comma]].

== Temperaments ==

Tempering out this comma in the full 13-limit defines the '''minismic''' temperament, ~~which~~ enables the [[minismic chords]], the essentially tempered ~~chords~~ in the [[21-odd-limit]]. You may find a list of good equal ~~temperaments~~ that support ~~this temperament~~ below.

[[Tempering out]] this comma in the full 13-limit defines the '''minismic''' temperament, or in the 2.3.5.7.13 subgroup, the '''minic''' temperament. In either case, it equates the tridecimal quartertone with the septimal one, and enables the [[minismic chords]], the [[essentially tempered chord]]s in the [[21-odd-limit]]. You may find a list of good [[equal temperament]]s that [[support]] these temperaments below.
