Generated by 3\13, the 276.9 cent minor third, this scale sounds a little like the octatonic scale in 12edo with an extra small step inserted. Two of these make a 11/8 and three make a 13/11~8/5, so very good for 8:11:13 triads. [[17edo]] also supports a similar 4L 5s scale, generated by 4\17 minor third. [[Orwell|Similar scales]] also in 22edo and 31edo with flatter generators, but they won't approximate the 13th harmonic. | Generated by 3\13, the 276.9 cent minor third, this scale sounds a little like the octatonic scale in 12edo with an extra small step inserted.

The brightest mode is 0-2-3-5-6-8-9-11-12-13; you get 8:11:13 on degrees 1, 2, 3, 5, 7 and 9. Since you get 21/16 as the minor version of 11/8, you also get a few 16:21:26's with the same interval classes. | The brightest mode is 0-2-3-5-6-8-9-11-12-13; you get 8:11:13 on degrees 1, 2, 3, 5, 7 and 9.
