'''472edo''' is the [[EDO|equal division of the octave]] into 472 parts of 2.54237 cents each. It is consistent to the 11-limit, tempering out 32805/32768 (schisma) and 1224440064/1220703125 (parakleisma) in the 5-limit; 2401/2400, 2460375/2458624, and 30623756184/30517578125 in the 7-limit; 9801/9800, 46656/46585, 117649/117612, and 234375/234256 in the 11-limit, [[support|supporting]] the [[Breedsmic temperaments|maviloid temperament]], the [[Schismatic family|bisesqui temperament]], and the [[Schismatic family|octant temperament]]. Using the patent val, it tempers out 729/728, 1575/1573, 2200/2197, 4096/4095, and 21168/21125 in the 13-limit, so it also supports the 13-limit octant.

It is a [[zeta peak integer edo]].
== Theory ==
472edo is [[enfactoring|enfactored]] in the 5-limit, with the same tuning as [[118edo]], defined by [[tempering out]] the [[schisma]] and the [[parakleisma]], but the approximation to higher harmonics are much improved. It is a [[zeta peak integer edo]], [[consistent]] to the [[11-odd-limit]] or the no-13 [[29-odd-limit]].  


{{Primes in edo|472|prec=3}}
In the 7-limit, the equal temperament tempers out [[2401/2400]], 2460375/2458624, and 30623756184/30517578125; in the 11-limit, [[9801/9800]], 46656/46585, 117649/117612, and 234375/234256, [[support]]ing the [[maviloid]] temperament, the [[Schismatic family #Bisesqui|bisesqui]] temperament, and the [[octant]] temperament. Using the [[patent val]], it tempers out [[729/728]], [[1575/1573]], [[2200/2197]], [[4096/4095]], and 21168/21125 in the 13-limit, so it also supports the 13-limit octant.
