The ''232 equal division'' divides the octave into 232 equal parts of 5.172 cents each. It provides the [[Optimal_patent_val|optimal patent val]] for [[13-limit|13-limit]] [[Hemifamity_temperaments#Mystery|mystery temperament]], the rank three [[Hemifamity_family#Pele|pele temperament]] and the rank three [[Trimyna_family#Trimyna-13-limit|trimyna temperament]] and other temperaments tempering out 196/195, for which it gives the optimal patent val for the corresponding rank five temperament.

Aside from its patent val, the 232d val is worth considering. Both temper out the wuerschmidt comma, 393216/390625, in the 5-limit.
== Theory ==
232 = 8 × 29, and 232edo shares its [[3/2|fifth]] with [[29edo]]. The equal temperament [[support]]s and provides the [[optimal patent val]] for the [[13-limit]] [[mystery]] temperament, the rank-3 [[pele]] temperament and the rank-3 [[trimyna]] temperament and other temperaments tempering out [[196/195]], for which it gives the optimal patent val for the corresponding rank-5 temperament.


In the 7-limit, the patent val tempers out hemifamity, 5120/5103 and the trimyna comma, 50421/50000; and 232d 3125/3097 and 245/243, [[support|supporting]] [[Sensamagic_clan#Bohpier|bohpier temperament]]. In the 11-limit, the patent val tempers out 441/440 and 896/891, and 232d 540/539, 1375/1372 and 4000/3993, supporting octoid. In the 13-limit, the patent val tempers out 196/195, 352/351, 364/363, 441/440 and 676/675, which leads to 13-limit mystery, for which it provides the optimal patent val. 232d also tempers out 352/351 and 676/675, which supports variants of octoid.  
Aside from its [[patent val]], the 232d val {{val| 232 368 539 '''652''' 803 859 }} is worth considering. Both temper out the [[würschmidt comma]], 393216/390625, in the 5-limit. In the 7-limit, the patent val tempers out hemifamity, [[5120/5103]] and the trimyna comma, [[50421/50000]]; and 232d [[4375/4374]] and [[16875/16807]], supporting [[octoid]]. In the 11-limit, the patent val tempers out [[441/440]] and [[896/891]], and 232d [[540/539]], 1375/1372 and [[4000/3993]]. In the 13-limit, the patent val tempers out 196/195, [[352/351]], [[364/363]], [[676/675]], and [[847/845]], which leads to 13-limit mystery, for which it provides the optimal patent val. 232d also tempers out 352/351 and 676/675, which supports a variant of octoid.  


Considering the 232edo patent val, 13-limit mystery and 13-limit pele, we note that because it tempers out 441/440 it allows [[werckismic_chords|werckismic chords]], because it tempers out 196/195 it allows [[mynucumic_chords|mynucumic chords]], because it tempers out 352/351 it allows [[minthmic_chords|minthmic chords]], and because it tempers out 364/363 it allows [[gentle_chords|gentle chords]], and because it tempers out 847/845 it allows the [[cuthbert_triad|cuthbert triad]], making it a very flexible harmonic system.
Considering the 232edo patent val, 13-limit mystery and 13-limit pele, we note that because it tempers out 441/440 it allows [[werckismic chords]], because it tempers out 196/195 it allows [[mynucumic chords]], because it tempers out 352/351 it allows [[major minthmic chords]], and because it tempers out 364/363 it allows [[minor minthmic chords]], and because it tempers out 847/845 it allows the [[cuthbert chords]], making it a very flexible harmonic system. 232edo is also the first edo that approximates [[6/5]] more accurately than [[19edo]].
