1-9-13-15 by 8/5 bihexany

A 13-limit Bihexany. This creates a scale of 1 13/12 52/45 13/10 4/3 65/48 13/9 3/2 8/5 13/8 5/3 15/8 2/1, with steps of 13/12 16/15 9/8 40/39 65/64 16/15 27/26 16/15 65/64 40/39 9/8 16/15. This cancels out some of the more complex ratios in the base hexany to fill in the large gap on one side and give you perfect fifths above & below the root note and one 5-limit major chord, at the cost of having two microtonal clusters which are below the optimal size for melody.
