<p>A cuboctahedron is a <a href="/facts/Polyhedron/UC0p9FTF">polyhedron</a> with 8 triangular faces and 6 square faces. A cuboctahedron has 12 identical <a href="/facts/Vertex_(geometry)/ID3cea9z">vertices</a>, with 2 triangles and 2 squares meeting at each, and 24 identical <a href="/facts/Edge_(geometry)/3lFN6sEz">edges</a>, each separating a triangle from a square. As such, it is a <a href="/facts/Quasiregular_polyhedron/1ukrFhec">quasiregular polyhedron</a>, i.e., an <a href="/facts/Archimedean_solid/wYWeHDYT">Archimedean solid</a> that is not only <a href="/facts/Vertex-transitive/5nC8PdBm">vertex-transitive</a> but also <a href="/facts/Edge-transitive/p5j7GhwX">edge-transitive</a>. It is radially equilateral. Its <a href="/facts/Dual_polyhedron/rkIHbmAf">dual polyhedron</a> is the <a href="/facts/Rhombic_dodecahedron/X3npAlmr">rhombic dodecahedron</a>. </p>
