1-9-11-13 hexany

A 13-odd-limit Hexany. This creates a scale of 1 11/9 11/8 13/9 13/8 143/72 2/1, with steps of 11/9 9/8 104/99 9/8 11/9 144/143. With a ratio of nearly 29:1 between the largest and smallest steps, making the smallest one barely in the noticeable range, this works better as a pentatonic scale than a hexatonic one. On the plus side, combining the two neutral thirds and the comma step results in a 5th of 706.88 cents, which is still close enough to just to provide a stable rooting point.
