1-3-15-17 hexany
A 17-odd-limit Hexany. This creates a scale of 1 17/16 5/4 85/64 17/12 15/8 2/1, with steps of 17/16 20/17 17/16 16/15 45/34 16/15. With 2 perfect fifths, one that is sharp by 136/135 and one that is sharp by 256/255, this is a quite consonant but not particularly xenharmonic scale that maps unambiguously to a subset of 12edo, although it lacks full major or minor chords despite having a fair number of good dyads.
