An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. So there are 257 examples, plus versions of these formed by stretching and twisting. Some simple octahedra are
- a regular octahedron (also known as a square-based dipyramid or triangular antiprism)
- heptagon-based pyramid
- hexagon-based prism.

How many perpendicular faces does a octahedron have?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of perpendicular faces will depend on which particular octahedron you have in mind. The heptagon-based pyramid, for example, has none.
