Geometric Model by A. Harry Wheeler, Third Stellation of the Icosahedron
name: label: maker
content: Wheeler, Albert Harry
notes: label: Description
content: Polyhedra in which all faces are equilateral triangles are called deltahedra. The regular tetrahedron, octahedron, and icosahedron are the simplest deltahedra. It also is possible to replace each face of a regular dodecahedron with a “dimple” having five equilateral triangles as sides. This is a model of such a surface. It also may be considered as one of the polyhedra formed by extending the sides of—or stellating—a regular icosahedron.
label: Description
content: This tan and gray deltahedron is folded from paper and held together entirely by hinged folds along the edges. A mark reads: 387. Another mark reads: 799' 12.
