An archimedean polyhedron.
N.6 of the complete set counting 13 items.
The truncated cuboctahedron has 26 faces (12 squares,
6 octagons), 72 edges and 48 vertices.
The Archimedean solids are bounded by two or more kinds of regular polygons, meeting at each vertex in the same identical way.
They were discovered by Archimedes in a now-lost work. In 1620 Johannes Kepler described them all and gave them the names still in use.
