3-7-9-13-15 dekany

A 15-odd-limit dekany. This creates a scale of 1 15/14 13/12 65/56 5/4 9/7 39/28 3/2 45/28 13/7 2/1, with steps of 15/14 91/90 15/14 14/13 36/35 13/12 14/13 15/14 52/45 14/13. With three perfect fifths, plus an additional one flat by 105/104, this is another negri-adjacent combination product set that is quite melodically and harmonically effective, but also has some small steps that are conflated in the regular temperament that cause dissonance when played together, giving it a wide variety of uses as long as you can deal with the fact that the fifths are all clustered on one side.
