Small dodecahemicosahedron

The small dodecahemicosahedron is a type of Archimedean solid, which is defined as a convex polyhedron with identical vertices and faces composed of regular polygons. Specifically, the small dodecahemicosahedron features 12 regular pentagonal faces and 20 regular triangular faces, giving it a distinct geometric structure. It can be classified under the category of dual polyhedra, where it serves as the dual of the icosahedron.
