111202 equal divisions of the octave (abbreviated 111202edo or 111202ed2), also called 111202-tone equal temperament (111202tet) or 111202 equal temperament (111202et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 111202 equal parts of about 0.0108 ¢ each. Each step represents a frequency ratio of 21/111202, or the 111202nd root of 2. It is the denominator of the next convergent for log23 past 79335, before 190537.

111202edo has a consistency limit of only 9, and is a strong 5-limit system, with additional strengths in the 2.3.5.17.19.23 subgroup.
