A 17-odd-limit Hexany. This creates a scale of 1 51/50 17/16 9/8 6/5 51/40 3/2 51/32 17/10 9/5 15/8 153/80 2/1, with steps of 51/50 25/24 18/17 16/15 17/16 20/17 17/16 16/15 18/17 25/24 51/50 160/153. As the base hexany has 3/2's and 5/4's, but no 6/5's, this is a fairly obvious way to give it some familiar chords, with 6 perfect fifths and two more imperfect but still diatonic ones sharp by 136/135 and 256/255. It does still have a large gap on one side and a cluster of microtones on the other, giving it some xenharmonic elements, but overall, it has more than enough familiar ones to compose tonal music with as well even if some keys will need to be mapped more than 100 cents away from 12edo on a standard keyboard.
