The '''94 equal divisions of the octave''' ('''94edo'''), or the '''94(-tone) equal temperament''' ('''94tet''', '''94et''') when viewed from a [[regular temperament]] perspective, results from dividing the [[octave]] into 94 [[equal]]ly-sized steps, where each step is about 12.8 [[cent]]s.

The list of 23-limit commas it tempers out is huge, but it is worth noting that it tempers out [[32805/32768]] and is thus a [[schismatic]] system, that it tempers out [[225/224]] and [[385/384]] and so is a [[marvel]] system, and that it also tempers out [[3125/3087]], [[4000/3969]], [[5120/5103]] and [[540/539]]. It provides the [[optimal patent val]] for the rank-5 temperament tempering out [[275/273]], and for a number of other temperaments, such as [[isis]].

94edo is an excellent EDO for [[Carlos Beta]] scale, since the difference between 5 steps of 94edo and 1 step of Carlos Beta is only -0.00314534 cents.

94et is lower in relative error than any previous equal temperaments in the 23-limit, and the next ET that does better in this subgroup is 193.

Since 94edo has a step of 12.766 cents, it also allows one to use its MOS scales as circulating temperaments and is the first edo to allows one to use a Mohajira, Pajara or Miracle MOS scale a as circulating temperament{{clarify}}.
