Icosahedron | DNA in another Dimension
Icosahedron is any polyhedrons have 20 faces, but generally a regular icosahedron is implied, which has equilateral triangles as faces.

Icosahedron
The regular icosahedron is one of the five Platonic solids. It is a curved regular polyhedron composed of 20 triangular faces, with five meeting at each of the twelve vertices. It has 30 edges and 12 vertices. Its twofold polyhedron is the dodecahedron.
