Researchers identified a shape that was previously only theoretical: a 13-sided configuration called “the hat” that can tile a surface without repeating. The hat is what’s known as an ...

In March, a group of mathematicians identified a thirteen-sided shape called “the hat” that can tile a surface without any patterns repeating. Now the researchers are updating the shape to ...

Polygons can be regular or irregular in shape. A polygon is a closed 2D shape with at least three sides. A regular polygon is a polygon with all equal sides and angles. An irregular polygon is a ...

A group of computer scientists discovered the first true "einstein" shape. The shape comes with 13 sides and can cover a plane without ever repeating. The find has applications in material science.

A new 13-sided shape is the first example of an elusive "einstein" — a single shape that can be tiled infinitely without repeating a pattern. When you purchase through links on our site ...
