7-9-11-13-15 dekany
The most complex 15-odd-limit Dekany. This creates a scale of 1 15/14 143/126 11/9 55/42 13/9 65/42 11/7 5/3 13/7 2/1, with steps of 15/14 1001/945 14/13 15/14 182/165 15/14 66/65 35/33 39/35 14/13. The step sizes are actually fairly even in this apart from one comma step of 66/65, but it completely misses any perfect fifths, making it quite effective melodically, but very xenharmonic. Working with it therefore requires figuring out how to make good use of other consonances in similar ways to edos like 11 and 13.
