What kind of polyhedron is this? I understand 20 faces is the largest regular polyhedron, but this one seems to have 36 faces.

(Incorrect) I think it is a Pentakis dodecahedron with $60$ faces, $90$ edges and $32$ vertices.
Here is the rotating model.
Edit: It is actually a Pentakis icosidodecahedron with $80$ triangles ($20$ equilateral; $60$ isosceles), $120$ edges and $42$ vertices. (See the comments below)
