A polyhedron of type (4,6,6)
The polyhedron in the photo is uniform: this means that around every vertex there are the same polygons (in the same order) and that if you take any couple of vertices in the polyhedron, you can always move the first one in the position of the second one. This feature allows us to identify a uniform polyhedron with some numbers: in the photo we see a (4,6,6).
