A 13-limit Hexany. This creates a scale of 1 65/48 13/9 13/8 5/3 15/8 2/1, with steps of 65/48 16/15 9/8 40/39 9/8 16/15. This is another lopsided hexany where all the intervals are on one side of the scale with a gap of nearly 600 cents on the other, making it easy to complete the circle by expanding it out into a bihexany without having any unusably small intervals, although at least one step of 65/64 is inevitable if you want access to 5-limit chords.
