1-5-9-17 by 10/7 bihexany

A 17-odd-limit Bihexany. This creates a scale of 1 17/16 9/8 17/14 9/7 153/112 10/7 85/56 45/28 17/10 9/5 153/80 2/1, with steps of 17/16 18/17 68/63 18/17 17/16 160/153 17/16 18/17 238/225 18/17 17/16 160/153. As the base hexany has ratios of 5 under half of its intervals, this translates them to septimal ones with minimal increase in complexity, creating a 12 note scale that does have some xenharmonic intervals in, but still maps unambiguously to a standard keyboard and has multiple fifths within the diatonic range, making it fairly easy to work with despite the lack of perfect ones.
