3476 equal divisions of the octave (abbreviated 3476edo or 3476ed2), also called 3476-tone equal temperament (3476tet) or 3476 equal temperament (3476et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 3476 equal parts of about 0.345 ¢ each. Each step represents a frequency ratio of 21/3476, or the 3476th root of 2.
3476edo is consistent to the 7-odd-limit, though it has large errors on harmonics 3 and 7. In the 7-limit, it tempers out the skeetsma. Aside from this, it is a strong 2.5.11.17.23 subgroup tuning.
