Steldia, an 18-note 7-limit scale

Here's an interesting 18-note 7-limit scale containing both a diamond
and a stellated hexany, with scale steps which are all
superparticulars. It can be derived from tetrads in the cuboid region
[-1..0,-1..0,-1..1], and contains both the [-1..0,-1..0,-1..0] diamond
and the [-1..0,-1..0,0..1] stellated hexany. Interval sizes range from
15/14 to 50/49.
