: Most of the math is due to GWS, who is good at math. Math is either correct or incorrect; there is hardly a third category for "unclear" unless you're Mochizuki. I would guess that this math in particular is correct. --[[User:Hkm|hkm]] ([[User talk:Hkm|talk]]) 16:46, 25 June 2025 (UTC)

: This math in particular makes a couple of logical leaps; these leaps were probably filled better by articles which this one linked to when all of the wiki was more math-focused. --[[User:Hkm|hkm]] ([[User talk:Hkm|talk]]) 17:00, 25 June 2025 (UTC)

: To understand the section about finding the epimorph val, do cofactor expansion on the top row, then realize that the monzos when stripped of (for example) their first coordinate span ALL the intervals which are octave-equivalent to the origin. In the example given, they span 1/22 of all the intervals since the determinant of those three monzos is 22, so 1/22 of all intervals must be octave-equivalent to the origin; thus our rank-1 temperament must map 2/1 to 22 steps.
