1092 equal divisions of the octave (abbreviated 1092edo or 1092ed2), also called 1092-tone equal temperament (1092tet) or 1092 equal temperament (1092et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1092 equal parts of about 1.1 ¢ each. Each step represents a frequency ratio of 21/1092, or the 1092nd root of 2.
1092edo is related to 364edo, but it differs in mapping for 5 and 11. Despite having large errors on harmonics, it is consistent in the 13-odd-limit. It is not consistent higher than that as its mapping for 15/8 is off by one step of a stack of 3/2 and 5/4. It provides the optimal patent val for the sextile temperament and the rank-3 loki temperament.
In higher limits, 1092edo is accurate in the 2.13.29.31.53.59 subgroup.

Subsets and supersets
Since 1092 factors into 22 × 3 × 7 × 13, 1092edo has subset edos 2, 3, 4, 6, 7, 12, 13, 14, 21, 26, 28, 39, 42, 52, 78, 84, 91, 156, 182, 273, 364, and 546.
