Theory

416et is consistent to the 7-odd-limit, but the error of harmonic 3 is quite large. Nonetheless, it gives reasonable approximations to harmonics 5, 7, 9, 11, 19, and 23, making it suitable for a 2.9.5.7.11.19.23 subgroup interpretation, where it notably tempers out 1331/1330, 1540/1539, 5632/5625, 9801/9800, and 10241/10240.

Using the patent val regardless, it tempers out 321489/320000, 589824/588245, and 703125/702464, supporting tridecatonic and fermionic.

Subsets and supersets

Since 416 factors into 2⁵ × 13, 416edo subset edos 2, 4, 8, 13, 16, 26, 32, 52, 104, and 208. 832edo, which doubles it, gives a good correction to the harmonic 3.
