There are several natural molecules and minerals whose structures are octahedral. Since these substances were in existence long before the first humanoid inhabited this planet, nobody can be said to have invented or made an octahedron.

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have triangles for all eight faces or, as is the case with a hexagonal prism, not a single triangular face.
An octahedron has 8 sides.An octahedron is a polyhedron with eight plane faces.
An octahedron has eight faces. If it has 62 faces then it is not an octahedron!

Start with an octahedron in the form of a quadrilateral based dipyramid a regular octahedron is a special case of this). This shape has six vertices - chop these off so as to remove a quadrilateral based pyramid. You will be left with a truncated octahedron. It is an octahedron which has been truncated (shortened) by cutting off its extremities.
An octahedron is not a polygon. A polygon is a two dimensional shape. An octahedron is a three dimensional shape and is classified as a polyhedron.
