The next two solids are rather special in that they can be derived from another Archimedian solid by the process of truncating the edges (and vertices). The Small Rhombicuboctahedron can derived by starting with either the Cube or the Octahedron and truncating the edges. Likewise, the Small Rhombicosidodecahedron can derived by starting with either the Icosahedron or the Dodecahedron.
A very nice screensaver that demonstrates this relationship can be obtained (for free!) here: Polyhedron Screensaver.
The following two solids are unusual in that they are not mirror symmetric; that is, there is a "left-handed" and a "right-handed" form of each. An object and its mirror image are enantiomorphs of each other. Solids which are not mirror symmetric are said to be chiral.
