The '''unicorn family''' tempers out the [[unicorn comma]], 1594323/1562500 = {{monzo| -2 13 -8 }}. The canonical extension to the 7-limit is by interpreting the generator as a slightly flattened [[~]][[28/27]] so that a flat [[~]][[6/5]] is found at 5 generators, corresponding to tempering [[126/125]], the [[octaphore]] and the [[hemimage comma]].
The '''unicorn family''' tempers out the [[unicorn comma]] ({{monzo|legend=1| -2 13 -8 }}, [[ratio]]: 1594323/1562500).

By noticing that the generator is very close to [[28/27]] we find the extension to the 7-limit by tempering the [[octaphore]] (which finds [[~]][[9/7]] at 7 gens and [[~]][[4/3]] at 8 gens, hence its name) and [[126/125]] (finding [[~]][[6/5]] at 5 gens). From this we can observe that the most natural extension is by equating adjacent [[superparticular interval]]s, by tempering the [[square-particular]]s between them, leading to its [[S-expression]]-based comma list of {[[676/675|S26]], [[729/728|S27]], [[784/783|S28]], [[841/840|S29]]}, to which experimentation shows we can find a reasonable mapping for prime 43 at -11 gens while all other primes require either quite complex mappings (being significantly positive rather than negative) or require high error or both.
Unicorn divides the [[4/3|perfect fourth]] into eight equal parts, three for [[10/9]] and five for [[6/5]]. Its [[ploidacot]] is omega-octacot.

The canonical extension to the 7-limit is by interpreting the generator as a very slightly flattened [[~]][[28/27]], corresponding to tempering out 126/125, the [[starling comma]], and 10976/10935, the [[hemimage comma]]. As it equates the perfect fourth with a stack of eight 28/27's, it also tempers out the [[octaphore comma]] in the [[2.3.7 subgroup]].


The hemifourth, reached by four generator steps, can be interpreted as ~[[15/13]]. This gives rise to a natural [[2.3.5.7.13 subgroup|2.3.5.7.13-subgroup]] extension where [[196/195]] and [[676/675]] vanish.
From 10976/10935 = ([[784/783]])<sup>2</sup>⋅([[841/840]]) we obtain an add-29 extension for free, so the generator triples as 28/27~[[29/28]]~[[30/29]], and as 196/195 vanishes already, so does [[729/728]], leading to its [[S-expression]]-based comma list of {[[676/675|S26]], [[729/728|S27]], [[784/783|S28]], [[841/840|S29]]}.
Experimentation shows we can find a reasonable mapping for prime 43 at -11 generator steps, tempering out [[216/215]]. All other primes require either quite complex mappings (being significantly positive rather than negative) or require high error or both.
In all the subgroups above, the optimum is between [[58edo]] and [[77edo]], though a notable tuning not appearing in the [[optimal ET sequence]]s here is [[96edo]] using the 96d val (with a 963{{c}} [[~]][[7/4]] similar to that of [[meanpop]]), which sacrifices the accuracy of prime 7 in favour of a more accurate 5.

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.

The unicorn family tempers out the unicorn comma (monzo: [-2 13 -8⟩, ratio: 1594323/1562500).

Unicorn

Unicorn divides the perfect fourth into eight equal parts, three for 10/9 and five for 6/5. Its ploidacot is omega-octacot.

Subgroup: 2.3.5

Comma list: 1594323/1562500

Badness (Sintel): 3.53

Septimal unicorn

The canonical extension to the 7-limit is by interpreting the generator as a very slightly flattened ~28/27, corresponding to tempering out 126/125, the starling comma, and 10976/10935, the hemimage comma. As it equates the perfect fourth with a stack of eight 28/27's, it also tempers out the octaphore comma in the 2.3.7 subgroup.

The hemifourth, reached by four generator steps, can be interpreted as ~15/13. This gives rise to a natural 2.3.5.7.13-subgroup extension where 196/195 and 676/675 vanish.

From 10976/10935 = (784/783)2⋅(841/840) we obtain an add-29 extension for free, so the generator triples as 28/27~29/28~30/29, and as 196/195 vanishes already, so does 729/728, leading to its S-expression-based comma list of {S26, S27, S28, S29}.

Experimentation shows we can find a reasonable mapping for prime 43 at -11 generator steps, tempering out 216/215. All other primes require either quite complex mappings (being significantly positive rather than negative) or require high error or both.

In all the subgroups above, the optimum is between 58edo and 77edo, though a notable tuning not appearing in the optimal ET sequences here is 96edo using the 96d val (with a 963 ¢ ~7/4 similar to that of meanpop), which sacrifices the accuracy of prime 7 in favour of a more accurate 5.

Rhinoceros

Rhinoceros tempers out the semaphoresma and the ragisma, identifying the generator as a ~21/20, rather than the 28/27 of septimal unicorn. It may be described as the 19 & 20c temperament. 19edo is a good tuning, though 39edo is a possible alternative.
