Platonic Solids 2 A regular tetrahedron and a regular octahedron are two of the five known Platonic Solids. These five “special” polyhedra look the same from any vertex, their faces are

### The FivePlatonic Solids

One might suppose that these forms are also infinite, but in fact they are, as Lewis Carroll once expressed it, "provokingly few in number."There are only five regular convex solids: the regular tetrahedron, hexahedron (cube), octahedron, dodecahedron, and icosahedron (see Figure 1).

### How "Shaky" Is The Jessen's Orthogonal Icosahedron ?

17 Octahedron And Cuboctahedron We mentioned earlier that octahedron and cuboctahedron can be defined as transformed icosahedra. You can also imagine the 6 square faces of the cuboctahedron as diagonal connections (1*sqrt2) of two rectangular triangles.

### Magnetic Teleportation Systems

When the device is switched 'on', the interior is isolated from its surroundings by the superluminal rotating magnetic field and octahedron antenna.
