1-7-9-13-15 dekany
A 15-odd-limit dekany. This creates a scale of 1 117/112 15/14 9/8 135/112 9/7 13/8 195/112 13/7 15/8 2/1, with steps of 117/112 40/39 21/20 15/14 16/15 91/72 15/14 16/15 105/104 16/15. With a very large gap on one side on the scale and multiple tiny ones on the other, this is a highly xenharmonic dekany that does have a few familiar melodic steps within it, but not positioned in a way that makes for full chords.
