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).

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.
An octahedron has 12 edges.It also has 8 faces and 6 vertices.Twelve (12).
