-'''313EDO''' is the [[EDO|equal division of the octave]] into 313 parts of 3.83387 [[cent]]s each. It provides the [[Optimal_patent_val|optimal patent val]] for 11- and 13-limit [[Porwell_temperaments#Hemischis|hemischis temperament]] and the rank three [[Cataharry_family|madagascar temperament]].
