Circle diagram.

A 7-limit Bihexany. This creates a scale of 1 21/20 9/8 6/5 21/16 7/5 3/2 63/40 42/25 7/4 9/5 15/8 2/1, with steps of 21/20 15/14 16/15 35/32 16/15 15/14 21/20 16/15 25/24 36/35 25/24 16/15. While there is still some clustering on one side of the scale, no note is smaller than a quartertone and there are 6 perfect 5ths & 2 marvellous ones, allowing for plenty of freedom to modulate.
