A hectahedron, also known as a hexadecagon in 2D or a polyhedron with 16 faces in 3D, typically refers to a polyhedron with 16 vertices. However, the specific number of vertices can vary depending on the type of hectahedron and its geometric properties. For example, a regular tetrahedron has 4 vertices, while a more complex form may have a different number.
