1-3-5-9 by 13/10 bihexany

A 13-limit Bihexany. This creates a scale of 1 13/12 9/8 39/32 5/4 13/10 117/80 3/2 13/8 5/3 15/8 39/20 2/1, with steps of 13/12 27/26 13/12 40/39 26/25 9/8 40/39 13/12 40/39 9/8 26/25 40/39. This expands the near-diatonic scale of the base hexany into a 12 note scale that maps decently to a standard keyboard with many simple consonant chords, including 8 notes with perfect fifths above them, each with a 5-limit major or minor third, but also contains multiple obviously xenharmonic intervals, giving you interesting new compositional options without adding an overwhelming number of them or placing any so close together that they blur into one-another.
