icosahedra

Platonic solid type

Icosahedra is the plural of icosahedron, a three-dimensional shape with twenty flat faces.

In geometry, a regular icosahedron has twenty equilateral triangles as faces—one of the five Platonic solids.

The twenty-sided die used in tabletop gaming is an icosahedron: Roll the icosahedra to determine your fate.
