|Triamond antiprism 2,2|
|Type||Convex triamond polyhedron|
|Faces||1 square, 2 trapezoids, 2 triangles|
|Measures (minor edge length 1)|
|Number of external pieces||5|
|Level of complexity||9|
|Abstract & topological properties|
|Discovered by||Roger Kaufman|
The triamond antiprism 2,2 is a convex triamond polyhedron. It can be made by augmenting a square pyramid with two tetrahedra on opposite triangular faces and combining co-planar faces in the result, or as a section of the triangular cupola.
It has the fewest vertices, faces and edges of any known convex triamond polyhedron.

The triamond antiprism 2,2 can be augmented with itself along its rhombic face to form another convex triamond polyhedron.
