Hemimean clan
The hemimean clan tempers out the hemimean comma, 3136/3125, with monzo [6 0 -5 2⟩. The head of this clan is the 2.5.7 subgroup temperament didacus, generated by a tempered hemithird of 28/25. Two generator steps make 5/4 and five make 7/4.
The second comma of the comma list determines which 7-limit family member we are looking at. These extensions, in general, split the syntonic comma into two, each for 126/125~225/224, as 3136/3125 = (126/125)/(225/224). Hemiwürschmidt adds 2401/2400; hemithirds adds 1029/1024; spell adds 49/48. These all use the same nominal generator as didacus.
Septimal passion adds 64/63, splitting the hemithird into a further two. Septimal meantone adds 81/80 as well as 126/125 and 225/224, splitting an octave plus the hemithird into two perfect fifths. Sycamore adds 686/675, splitting the hemithird into three. Semisept adds 1728/1715, splitting an octave plus the hemithird into three. Mohavila adds 135/128, whereas cohemimabila adds 65536/64827, both splitting two octaves plus the hemithird into three. Emka adds 84035/82944, splitting two octaves plus the hemithird into four. Bidia adds 2048/2025 with a 1/4-octave period. Misty adds 5120/5103 with a 1/3-octave period. Bischismic adds 32805/32768 with a semioctave period. Hexe adds 50/49 with a 1/6-octave period. Clyde adds 245/243 with a generator of ~9/7, five of which make the original. Parakleismic adds 4375/4374 with a generator of ~6/5. Arch adds 5250987/5242880 with a generator of ~64/63. For these seven generators make the original. Sengagen adds 420175/419904 with a generator of ~686/675, splitting the hemithird into eight. Subpental adds 19683/19600 with a generator of ~56/45, nine of which make the original.

Roulette
In the no-3's 11-limit, there is a natural extension with prime 11 by equating 25/16 (which is already tuned sharp anyways) with 11/7 by tempering out 176/175, which is the same route that undecimal meantone uses, as this is essentially a no-3's restriction of undecimal meantone in the 11-limit, except that undecimal meantone finds ~28/25 at 2 generators (as a flat ~9/8) while here it is the generator. This whole tone generator serves as the two simplest mediants of 9/8 and 10/9, namely 19/17 and 28/25.
In the no-3's 13-limit, this temperament is hemiwur without a mapping for prime 3. The mapping of prime 13 is somewhat strange, because it is the only mapping that requires a negative amount of generators, and not by an insignificant amount, but it can be rationalized in a variety of ways, such as that because ~8/7 is already tuned considerably flat, it makes sense to equate two of it with 13/10, as this is also how we find 22/17 in the no-3's 17-limit. The mapping of 13 increases the badness of the temperament as a result.

Mediantone
Mediantone is named after its whole tone generator serving as the mediant of 9/8 and 10/9, namely 19/17, in addition to 28/25, as well as by the observation that this temperament seems to have been repeatedly rediscovered in parts in a variety of contexts, so that it seems to exist as a "median" of all of these temperaments' logics. It is also an intentional play on "meantone", as the context one is most likely to first discover this logic is when the tone also represents 10/9~9/8.
In the full no-3's 19-limit, this temperament is a structure common to quite a few temperaments. It is a rank-2 version of orion with a mapping for primes 11 and 13. It is a no-3's version of 19-limit grosstone which can be seen as an extension of undecimal meantone according to the "mediant-tone" logic of this temperament, and which as aforementioned effectively doubles the complexity of the temperament as a result of finding the generator of ~19/17~28/25 as (~3/2)2/2. It does not work so well as an extension for hemiwur to the full 19-limit, but if you want to try anyway, a notable patent-val tuning is 37edo, which finds prime 3 through the würschmidt mapping so that 6/1 is found at 16 generators.

Rectified hebrew
Rectified hebrew (37 & 56) is derived from the calendar by the same name. It is leap year pattern takes a stack of 18 Metonic cycle diatonic major scales and truncates the 19th one down to its generator, 11. It adds harmonic 13 through tempering out 4394/4375 and spliting the generator of didacus in three.

Hemiwürschmidt
Hemiwürschmidt (sometimes spelled hemiwuerschmidt) is not only one of the more accurate extensions of didacus, but also the most important extension of 5-limit würschmidt, even with the rather large complexity for the fifth. It tempers out 2401/2400, 3136/3125, and 6144/6125. 68edo, 99edo and 130edo can all be used as tunings, but 130 is not only the most accurate, it shows how hemiwürschmidt extends to a higher limit temperament, ⟨⟨ 16 2 5 40 -39 -49 -48 28 … ]].

Semisept
- For the 5-limit version of this temperament, see High badness temperaments #Semisept.
The minimal generator of semisept is half a tempered septimal major sixth (12/7), hence the name. Three such generator steps minus an octave give the hemithird, and six give the classical major third. It can be described as the 31 & 80 temperament, and as one may expect, 111edo makes for a great tuning.

Emka
- For the 5-limit version of this temperament, see High badness temperaments #Emka.
Emka tempers out [-50 -8 27⟩ in the 5-limit. This temperament can be described as 37 & 50 temperament, which tempers out the hemimean and 84035/82944 (quinzo-ayo). Alternative extension emkay (87 & 224) tempers out the same 5-limit comma as the emka, but with the horwell (65625/65536) rather than the hemimean tempered out.

Decipentic
The generator for the decipentic temperament (43 & 56) is the tenth root of the 5th harmonic (5/1), 51/10, tuned between 75/64 and 20/17 (close to 27/23). Aside from the hemimean comma, this temperament tempers out the bronzisma, 2097152/2083725. 99edo is a good tuning for decipentic, with generator 23\99, and mos scales of 9, 13, 17, 30, 43 or 56 notes are available.

Tremka
The name tremka was initially used for the no-sevens version of 50 & 111 (especially in the 2.3.5.11.13 subgroup), but extending to full 13-limit or higher prime limit does no significant tuning damage, so for that we keep the 2.3.5.11.13 label tremka.

Undetrita
The undetrita temperament (111 & 118) tempers out the hemimean comma (3136/3125) and skeetsma (14348907/14336000) in the 7-limit; 3025/3024, 3388/3375, and 8019/8000 in the 11-limit. This temperament is related to 11edt, and the name undetrita is a play on the words undecimus (Latin for "eleventh") and tritave (3rd harmonic). It is also related to the twentcufo temperament, which is no-sevens version of 111 & 118.
