'''491EDO''' is the [[EDO|equal division of the octave]] into 491 parts of 2.44399 [[cent]]s each. In the 5-limit it tempers out the parakleima, |8 14 -13>; in the 7-limit 65625/65536 and 420175/419904; in the 11-limit 441/440 and 8019/8000; in the 13-limit 729/728 and 4225/4224, and provides the [[Optimal_patent_val|optimal patent val]] for 11-limit [[Werckismic_temperaments#History|history temperament]], tempering out 441/440 and 4000/3993.

In the 5-limit the equal temperament tempers out the parakleisma, [8 14 -13; in the 7-limit 65625/65536 and 420175/419904; in the 11-limit 441/440 and 8019/8000; in the 13-limit 729/728 and 4225/4224, and provides the optimal patent val for 11-limit history, tempering out 441/440 and 4000/3993.
