m Theory: some commentary
Theory: hide the second table by default to reduce the noise on the page. And since we're at 71, I don't see a reason to shy away from presenting the qualities of primes as high as 89

In higher limits it excels as a subgroup temperament, especially as an incomplete 71-limit temperament with [[128/127]] and [[129/128]] (the subharmonic and harmonic comma-sized intervals, respectively) mapped accurately to a single step. Generalizing a single step of 87edo harmonically yields harmonics 115 through 138*, (thus) tempering S116 through S137 by patent val and corresponding to the gravity of the fact that 87edo is a circle of [[126/125]]'s, meaning ([[126/125]])<sup>87</sup> only very slightly exceeds the octave.

Generalizing a single step of 87edo harmonically yields harmonics 115 through 138, which when detempered is the beginning of the construction of [[Ringer scale|Ringer]] 87, thus tempering S116 through S137 by patent val and corresponding to the gravity of the fact that 87edo is a circle of [[126/125]]'s, meaning ([[126/125]])<sup>87</sup> only very slightly exceeds the octave.


(*When detempered this is the beginning of the construction of [[Ringer scale|Ringer]] 87.)
