Cells 15 1 cuboctahedron
6 square pyramids
8 triangular pyramids
Faces 38: (8+24) triangles
6 squares
Edges 36
Vertices 13
Dual rhombic dodecahedral pyramid
Symmetry group BC3, [4,3,1], order 48
Properties convex

In 4-dimensional geometry, the cuboctahedral pyramid is bounded by one cuboctahedron on the base, 6 square pyramid, and 8 triangular pyramid cells which meet at the apex. It has 38 faces: 32 triangles and 6 squares. It has 32 edges, and 13 vertices.

Since a cuboctahedron has a circumradius divided by edge length equal to one,[1] the triangles must be taller than equilateral to create a positive height.

The dual to the cuboctahedral pyramid is a rhombic dodecahedral pyramid, seen as an dodecahedral base, and 8 rhombic pyramids meeting at an apex.
