The '''431 equal divisions of the octave''' ('''431edo'''), or the '''431(-tone) equal temperament''' ('''431tet''', '''431et''') when viewed from a [[regular temperament]] perspective, is the [[EDO|equal division of the octave]] into 431 parts of about 2.78 [[cent]]s each.

431edo is [[consistent]] to the [[15-odd-limit]], tempering out the [[schisma]] in the 5-limit; [[2401/2400]] in the 7-limit; [[5632/5625]] and [[8019/8000]] in the 11-limit; [[729/728]], [[1001/1000]], [[1716/1715]], [[4096/4095]], [[6656/6655]] and [[10648/10647]] in the 13-limit. It [[support]]s the [[sesquiquartififths]] temperament.
