The hendecatonic temperament has a period of 1/11 octave, which represents [[16/15]] and four times of which represent [[9/7]]. It tempers out 10976/10935, the [[hemimage comma]], and may be described as the {{nowrap| 22 & 99 }} temperament, with [[99edo]] giving an almost perfect tuning.

== Twothirdtonic ==
== Nessafof ==
Twothirdtonic tempers out 686/675, the [[senga]], in addition to the porwell comma, and may be described as the {{nowrap| 37 & 46 }} temperament, generated by one third of a [[5/4|classical major third]] that represents [[15/14]], [[14/13]], and [[13/12]] in the [[13-limit]] interpretation. Note that in the data below, the generator is taken to be its [[octave complement]], thirteen of which [[octave reduction|octave reduced]] make the [[3/2|perfect fifth]]; it follows that the [[ploidacot]] for this temperament is 11-sheared 13-cot. [[46edo]] may be recommended as a tuning.

Also named by [[Petr Pařízek]] in 2011, ''aufo'' refers to the augmented fourth, which is a generator of this temperament<ref name="petr's long post"/>. The functional generator however is the [[64/45]] diminished fifth, and like its [[untriton]] variant, nine generator steps give the [[interval class]] of [[3/1|3]]. The [[ploidacot]] for this temperament is delta-enneacot.

Polypyth tempers out the same 5-limit comma as [[leapday]], with which it shares the similarly sharp [[3/2|perfect-fifth]] generator, but the porwell comma (6144/6125) rather than the hemifamity comma (5120/5103) is tempered out here.

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

This is a collection of temperaments that temper out the porwell comma (monzo: [11 1 -3 -2⟩, ratio: 6144/6125).

Temperaments discussed elsewhere are:

Considered below are hendecatonic, nessafof, grendel, aufo, absurdity, polypyth, whoops, dodifo, and icositritonic, in the order of increasing badness.

Hendecatonic

For the 5-limit version, see Miscellaneous 5-limit temperaments #Hendecatonic.

The hendecatonic temperament has a period of 1/11 octave, which represents 16/15 and four times of which represent 9/7. It tempers out 10976/10935, the hemimage comma, and may be described as the 22 & 99 temperament, with 99edo giving an almost perfect tuning.

Subgroup: 2.3.5.7

Nessafof

For the 5-limit version, see Miscellaneous 5-limit temperaments #Nessafof.

Cryptically named by Petr Pařízek in 2011[1], nessafof adds the landscape comma and has a third-octave period. The name actually refers to the fact that it has a neutral-second generator, and that a semi-augmented fourth, stacked five times, makes 5/1[2].

Aufo

For the 5-limit version, see Miscellaneous 5-limit temperaments #Untriton.

Also named by Petr Pařízek in 2011, aufo refers to the augmented fourth, which is a generator of this temperament[2]. The functional generator however is the 64/45 diminished fifth, and like its untriton variant, nine generator steps give the interval class of 3. The ploidacot for this temperament is delta-enneacot.

Polypyth

For the 5-limit version, see Miscellaneous 5-limit temperaments #Leapday.

Polypyth tempers out the same 5-limit comma as leapday, with which it shares the similarly sharp perfect-fifth generator, but the porwell comma (6144/6125) rather than the hemifamity comma (5120/5103) is tempered out here. It may be described as the 46 & 121 temperament, and 121edo and 167edo make for good tunings.

Dodifo

For the 5-limit version, see Miscellaneous 5-limit temperaments #Dodifo.

Also named by Petr Pařízek in 2011, dodifo refers to the (tetraptolemaic) double-diminished fourth, which is a generator of this temperament[2]. The extension here is a less accurate 7-limit interpretation.

Icositritonic

See also: 23rd-octave temperaments

Icositritonic has a period of 1/23 octave, so six period represents 6/5 and nine period represents 21/16. It may be described as 46 & 161. It was named by Xenllium in 2019 for its number of periods per octave.
