Template:EDO intro

3178edo is quite accurate in the 23-limit, consistent to the 27-odd-limit, and has an exceptional approximation of harmonic 13. However, like most edos of this size, it is rather impractical to use. It tempers out several of the smaller 23-limit superparticular commas, including 9801/9800 in the 11-limit; 10648/10647 and 123201/123200 in the 13-limit; 5832/5831, 14400/14399, and 28561/28560 in the 17-limit; 6175/6174, 10830/10829, 12636/12635, 14080/14079, 14365/14364, 23409/23408, 28900/28899, and 43681/43680 in the 19-limit; 8625/8624, 11271/11270, 12168/12167 and 43264/43263 in the 23-limit.
