1-5-7-9-13 dekany
A 13-odd-limit dekany. This creates a scale of 1 9/8 91/80 13/10 7/5 117/80 63/40 13/8 7/4 9/5 2/1, with steps of 9/8 91/90 8/7 14/13 117/112 14/13 65/63 14/13 36/35 10/9. This roughly approximates 6edo, with no perfect fifths but multiple close clusters of notes, all of different sizes that create different kinds of dissonance when played together, making it highly xenharmonic, but in quite an accessible way that still allows for a wide variety of sounds.
