1106 equal divisions of the octave (abbreviated 1106edo or 1106ed2), also called 1106-tone equal temperament (1106tet) or 1106 equal temperament (1106et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1106 equal parts of about 1.08 ¢ each. Each step represents a frequency ratio of 21/1106, or the 1106th root of 2.

Theory

1106edo is a zeta peak edo. It is strong as a 7-limit system; the only edos lower than it with a lower 7-limit relative error being 171, 270, 342, 441, and 612. It is even stronger in the 11-limit; the only ones beating it out now being 270, 342, and 612. It is less strong in the 13- and 17-limit, but even so is distinctly consistent through the 17-odd-limit.

The equal temperament tempers out [-53 10 16⟩ (kwazy comma) and [-13 -46 37⟩ (supermajor comma) in the 5-limit; 4375/4374 and 52734375/52706752 in the 7-limit; 3025/3024 and 9801/9800 in the 11-limit; 4096/4095, 78125/78078, and 105644/105625 in the 13-limit; 2500/2499, 4914/4913, and 8624/8619 in the 17-limit. It notably supports supermajor, brahmagupta, and orga in the 7-limit, and semisupermajor in the 11-limit. In the higher limits, it supports the 79th-octave temperament gold.
