There are different kinds of octahedra with different numbers of vertices and edges.
A truncated Octahedron has 36 edges.
It has 14 Faces, 24 Edges, and 12 Vertices
12 Faces, 30 Edges, 12 vertices
An octahedron has8 faces, 12 to 18 edges and 6 to 12 edges.

An octahedron has 8 faces, 12 edges, and 6 corners.
An octahedron has eight faces. If it has 62 faces then it is not an octahedron!
A stellated octahedron is the 3-D shape formed when two regular tetrahedra (triangular pyramids) which point in opposite directions are made to intersect. This is analogous to two equilateral triangles being drawn so that they form a hexagram (or Star of David).
In an octahedron, four edges meet at each vertex. An octahedron has eight triangular faces, twelve edges, and six vertices, with each vertex being the meeting point of four edges.

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have 12 to 18 edges.
An octahedron is a 3-dimensional shape with 8 faces. There are 257 topologically distinct convex octahedra, They can have a maximum of 18 edges.
