A 17-odd-limit Hexany. This creates a scale of 1 17/16 3/2 51/32 17/10 15/8 2/1, with steps of 17/16 24/17 17/16 16/15 75/68 16/15. This is one of those hexanies that is not particularly xenharmonic, as it is basically just a subset of 12edo, but it is still an awkward one that completely misses having any simple chords despite having both 3/2's and 5/4's in it. Even turning it into a bihexany with an interval near 600 cents will not be particularly optimal, as it will result in multiple blurry microsteps rather than a full approximation of 12edo.
