m →Temperaments: made order more conducive to reading for the purpose of distinguishing the variant on the base "archagall" name (by grouping together its variations as close as logically possible in the writing). this also naturally synergises with the prior change of swapping the order of "mavka" and "archagallismic" for the rank 6 temperament specifically. also capitalised AKA for aforementioned reasons

Tempering out this comma in the full [[17-limit]] results in the rank-6 '''mavka temperament''' AKA '''archagallismic'''. Tempering it out in the 2.3.5.17 subgroup results in the rank-3 '''archagallic temperament'''. If we restrict it to the 2.75.85 subgroup, we get the rank-2 '''archagall temperament'''. You may find a list of good equal temperaments supporting them below.

You may find a list of good equal temperaments supporting them below. The rank 6 temperament can be thought of as being equivalent to the [[17-limit]] with the exception that 5/4 is reached by going down by 17/16 three times, starting at 3/2. In other words, [[5/4]] = ([[3/2]])/([[17/16]])<sup>3</sup>. Similarly, archagallic can be thought of as the 2.3.5.17 subgroup with that same equivalence (so that it is essentially being expressed through 2.3.17). Archagall has its own, more complex mapping of prime 5 at +13 archagall fourths ([[85/64]]'s) (octave-reduced; specifically: minus five octaves).
