Theory

476edo is consistent to the 7-odd-limit and the harmonic 3 is about halfway its steps. Using the patent val, it tempers out 2401/2400 in the 7-limit; 4000/3993, 12005/11979, 117649/117612, 1296000/1294139, 540/539, 441/440, 352947/352000, 24057/24010, 8019/8000, 9801/9800 and 160083/160000 in the 11-limit.

Subsets and supersets

476 factors into 22 × 7 × 17, with subset edos 2, 4, 7, 14, 17, 28, 34, 68, 119, and 238. 952edo, which doubles it, gives a good correction to the harmonic 3, but unfortunately it is unconsistent in the 5-odd-limit.
