The dual of a truncated regular polyhedron is face-transitive with faces
shaped like isosceles triangles. Face transitivity means that for any
two faces of the polyhedron, there exists a translation, rotation, and/or
reflection that leaves the outward appearance of the polyhedron unchanged
yet moves one face to the other. There are five truncated regular duals
that are not self-intersecting, namely the
Triakis Tetrahedron, the
Tetrakis Hexahedron, the
Triakis Octahedron, the
Pentakis Dodecahedron, and the
Triakis Icosahedron.
When self-intersection is allowed, there are five other truncated regular
duals.
