'''118edo''' is the [[equal division of the octave]] into 118 parts of 10.1695 cents each.  
'''118edo''' is the [[equal division of the octave]] into 118 parts of 10.1695 cents each.  


118edo represents the intersection of the [[5-limit]] [[schismatic]] and [[parakleismic]] temperaments, [[tempering out]] both the [[schisma]], {{monzo|-15 8 1}} and the [[parakleisma]], {{monzo|8 14 -13}}, as well as the [[vishnuzma]], {{monzo|23 6 -14}}, the [[hemithirds comma]], {{monzo|38 -2 -15}}, and the [[kwazy]], {{monzo|-53 10 16}}. It is the first 5-limit equal division which clearly gives microtempering, with errors well under half a cent.

In the 7-limit, it is particularly notable for tempering out the [[gamelisma]], 1029/1024, and is an excellent tuning for the rank three [[Gamelismic family|gamelan]] temperament, and for [[guiron]], the rank two temperament also tempering out the schisma, 32805/32768. It also tempers out 3136/3125, the hemimean comma, but [[99edo]] does better with that.
