5-9-13-15 hexany
A 15-odd-limit Hexany. This creates a scale of 1 13/12 13/10 13/9 3/2 5/3 2/1, with steps of 13/12 6/5 10/9 27/26 10/9 6/5. Like several of it's immediate neighbours, this has both 3/2's and 6/5's in it, but no 5/4's, making it quite melodically interesting, but lacking the most stable chords that people who use 12edo are familiar with unless expanded into a bihexany, most of which will introduce intervals that are too small to be melodically useful.
