It’s a seven sided shape where all faces have the same surface area, which didn’t exist in the physical universe until it was discovered/invented by an artist over many years and many attempts. When the corners and edges are rounded it is the same shape as one ventricle of the human heart. There are many other forms in nature based on this shape. See the link, second video, long but very interesting if you have the patience to watch.

Then my comment may qualify as the most bizarre trading advice on record.
