^{3}× 32251**258008 equal divisions of the octave** (abbreviated **258008edo** or **258008ed2**), also called **258008-tone equal temperament** (**258008tet**) or **258008 equal temperament** (**258008et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 258008 equal parts of about 0.00465 ¢ each. Each step represents a frequency ratio of 2^{1/258008}, or the 258008th root of 2.

It is notable as a high-limit tuning system and is especially strong in the 13-limit, although it's also somewhat impractical given the vast density of notes. It is the first non-trivial EDO to be consistent in the 36-odd-prime-sum-limit.
