Circle diagram (rotated).

A 13-odd-limit Hexany. This creates a scale of 1 13/12 13/10 3/2 9/5 39/20 2/1, with steps of 13/12 6/5 15/13 6/5 13/12 40/39. With two notes with perfect fifths above to root them plus useful barbados thirds for each of them, this is a particularly effective hexany both melodically and harmonically, giving it strong compositional potential, particularly when expanded outwards into a dekany or bihexany.
