The polyhedron is obtained on the basis of the operation of mathematical expansion (for more detail, No. 21 of the Magic Edges).
A small rhombicuboctahedron is a semi-regular convex polyhedron with two properties:
1. All faces are regular polygons of two types - tegon and square;
2. For any pair of vertices, there is a symmetry of the polyhedron (that is, a motion that translates the polyhedron into itself) that transforms one vertex to another.
The small rhombicuboctahedron is one of the 13 solids of Archimedes.
Archimedean solids are semiregular polyhedra in the sense that their faces are regular polygons, but they are not the same, while the condition of one of the types of spatial symmetry: tetrahedral, octahedral or icosahedral is preserved.

Small rhombicuboctahedron from the set "Magic Edges"
To do this, you need to use the details of the set Magic Edges 21.
In addition, in the release itself you will find information about the structure of the polyhedron.
