5585 equal divisions of the octave (abbreviated 5585edo or 5585ed2), also called 5585-tone equal temperament (5585tet) or 5585 equal temperament (5585et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 5585 equal parts of about 0.215 ¢ each. Each step represents a frequency ratio of 21/5585, or the 5585th root of 2. It is a zeta peak edo, which has to do with the fact that it is a strong 13-limit division, with a lower 13-limit relative error than any smaller edo, though 6079, only slightly larger, beats it. A basis for its 13-limit commas is {123201/123200, 151263/151250, 8858304/8857805, 8859375/8859136, 62752536/62748517}.
