Great icosihemidodecahedron

The great icosihemidodecahedron, or geihid, is a quasiregular polyhedron and one of 10 uniform hemipolyhedra. It consists of 20 equilateral triangles and 6 central decagrams, with two of each joining at a vertex.

It is a faceting of the great icosidodecahedron, keeping the original's triangles while also using its equatorial decagrams.
