73709 equal divisions of the octave (abbreviated 73709edo or 73709ed2), also called 73709-tone equal temperament (73709tet) or 73709 equal temperament (73709et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 73709 equal parts of about 0.0163 ¢ each. Each step represents a frequency ratio of 21/73709, or the 73709th root of 2.
While it is distinctly consistent through the 11-odd-limit, its notability stems from the fact that it is a very strong 5-limit division, with lower 5-limit relative error than any smaller edo. However, 78005edo, only slightly larger, beats it. It tempers out [21 290 -207⟩ and [-573 237 85⟩ (quark) in the 5-limit.
