A new sphere made with 180 dots is used to build the unit upon. This sphere is quite interesting, as the magnets do not form the corners of any Catalan solid and because there are pentagonal faces with non-regular pentagons, it is also neither a Archimedian, nor a Platonic, nor a Johnson solid. It does form a solid with 12 regular pentagons (golden), 60 non-regular pentagons (3 golden and 2 blue dots each), 80 regular triangles (60 golden and 20 blue) and finally 60 triangles of which I'm not sure if they are regular or not (2 golden dots and a blue dot each), colors as used in the sphere with 12 pentagonal stars. This accounts for a polyhedron with 212 faces, a lot more faces then any Archimedian, Catalan or Johnson solid.
The way the units are connected is in the style often used by ledwatchman, who has many sphere based builds.
