Circle diagram.

A 15-odd-limit bihexany. This creates a scale of 1 35/32 9/8 7/6 5/4 21/16 45/32 35/24 3/2 105/64 7/4 15/8 2/1, with steps of 35/32 36/35 28/27 15/14 21/20 15/14 28/27 36/35 35/32 16/15 15/14 16/15. This extends the basic archy scale of the 1-3-7-9 hexany into a 12 note scale with 8 perfect 5ths and multiple simple 5-limit chords, with no intervals smaller than a quarter-tone, making it harmonically excellent and melodically fairly good as well, although not all of the 5ths are mapped to 7 steps above their roots.
