1059 equal divisions of the octave (abbreviated 1059edo or 1059ed2), also called 1059-tone equal temperament (1059tet) or 1059 equal temperament (1059et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1059 equal parts of about 1.13 ¢ each. Each step represents a frequency ratio of 21/1059, or the 1059th root of 2.
1059edo is inconsistent to the 5-odd-limit and harmonic 3 is about halfway between its steps, lending itself to a 2.9.5.7.13 subgroup interpretation.
103 steps of 1059edo represent a continued fraction approximation for the secor generator interval in the form of 46/43. In the 2.3.5.7.11.23.43 subgroup this results in a 329 & 1059 temperament. The comma basis for such (assuming both patent vals) is 1376/1375, 2646/2645, 172032/171875, 16401231/16384000, 51759729/51536320.

Subsets and supersets
Since 1059 factors into 3 × 353, 1059edo contains 3edo and 353edo as subsets. 2118edo, which divides the edostep in two, provides a good correction for 3rd and 11th harmonics.
