453 equal divisions of the octave (abbreviated 453edo or 453ed2), also called 453-tone equal temperament (453tet) or 453 equal temperament (453et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 453 equal parts of about 2.65 ¢ each. Each step represents a frequency ratio of 21/453, or the 453rd root of 2.
The equal temperament tempers out [8 14 -13⟩ (parakleisma) and [54 -37 2⟩ (monzisma) in the 5-limit; 250047/250000, 589824/588245, and 2460375/2458624 in the 7-limit; 3025/3024, 5632/5625, 24057/24010, and 102487/102400 in the 11-limit; 676/675, 1001/1000, 4096/4095, 6656/6655, and 16848/16807 in the 13-limit, so that it supports the monzismic temperament.
