The satin temperament (94 & 217) uses [[11/10]] as a generator, three of them gives [[4/3]], and tempers out both the [[rainy comma]] and the canousma.
Named by [[Xenllium]] in 2021, hemiquindromeda tempers out the [[decovulture comma]]. It is essentially a 24-form, and may be described as the 193 & 217 temperament. It splits the [[4/3|perfect fourth]] in ten [[~]][[36/35]] quartertone generators, thus having a [[ploidacot]] signature of omega-decacot. Three generator steps reach an accurate ~[[12/11]], from which we can derive an 11-limit extension where [[14700/14641]], [[16384/16335]], and [[19712/19683]] are tempered out, and a 13-limit extension that follows from 67108864/66976875 = ([[676/675]])⋅([[4096/4095]])<sup>2</sup>.

Subgroup: 2.3.5.7.11.13.17.19.23
Superlimmal is essentially an 80-form, and may be described as the {{nowrap| 80 & 311 }} temperament. It uses an ever slightly sharpened [[27/25|large limma]] as the generator, nine exceed the octave by [[126/125]]. Note that in the data that follow, the generator is its [[octave complement]], [[~]][[50/27]], so that 57 of them [[octave reduction|octave reduced]] make the [[3/2|perfect fifth]].

Superlimmal gets all the primes up to [[29/1|29]] reasonably covered, but is acceptable just as a 13-limit microtemperament, given a relatively simple [[comma basis]]. It can also be extended to include prime [[37/1|37]] by mapping it to 87 generator steps, tempering out ([[27/25]])/([[40/37]]) = [[1000/999]]. Since 40/37 is the mediant of [[27/25]] and [[13/12]], this extension further consolidates the sharpened limma.  
 
== Superlimmal ==
The superlimmal temperament (80 &amp; 311) uses an ever slightly sharpened [[27/25|large limma]] as the generator, nine exceed the octave by [[126/125]]. It gets all the primes up to 29 reasonably covered, but still acceptable just as a 13-limit microtemperament, judging from its [[comma basis]]. While the [[mos scale]] may not be the most effective approach, the 80-tone mos is presumably the place to start if it is used. It can also be extended to prime 37 by tempering out ([[27/25]])/([[40/37]]) = [[1000/999]], where 40/37 is notably the mediant of [[27/25]] and [[13/12]], which could be interpreted as an explanation of the sharpened limma.

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 page collects rank-2 cathartic temperaments, which temper out the cathartic comma (monzo: [4 -14 3 4⟩, ratio: 4802000/4782969). For the family of rank-3 temperaments, see Cathartic family.

Temperaments discussed elsewhere are:

Considered below are hemiquindromeda and superlimmal, in the order of increasing badness.

Hemiquindromeda

For the 5-limit version, see Schismic–commatic equivalence continuum #Quindromeda.

Named by Xenllium in 2021, hemiquindromeda tempers out the decovulture comma. It is essentially a 24-form, and may be described as the 193 & 217 temperament. It splits the perfect fourth in ten ~36/35 quartertone generators, thus having a ploidacot signature of omega-decacot. Three generator steps reach an accurate ~12/11, from which we can derive an 11-limit extension where 14700/14641, 16384/16335, and 19712/19683 are tempered out, and a 13-limit extension that follows from 67108864/66976875 = (676/675)⋅(4096/4095)2.

Superlimmal

Superlimmal is essentially an 80-form, and may be described as the 80 & 311 temperament. It uses an ever slightly sharpened large limma as the generator, nine exceed the octave by 126/125. Note that in the data that follow, the generator is its octave complement, ~50/27, so that 57 of them octave reduced make the perfect fifth.

Superlimmal gets all the primes up to 29 reasonably covered, but is acceptable just as a 13-limit microtemperament, given a relatively simple comma basis. It can also be extended to include prime 37 by mapping it to 87 generator steps, tempering out (27/25)/(40/37) = 1000/999. Since 40/37 is the mediant of 27/25 and 13/12, this extension further consolidates the sharpened limma.
