31202 equal divisions of the octave (abbreviated 31202edo or 31202ed2), also called 31202-tone equal temperament (31202tet) or 31202 equal temperament (31202et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 31202 equal parts of about 0.0385 ¢ each. Each step represents a frequency ratio of 21/31202, or the 31202nd root of 2.

31202edo approximates all harmonics up to the 23-odd-limit with less than 25% relative error.
