WebThe great icosahedron is one of the four regular star Kepler-Poinsot polyhedra.Its Schläfli symbol is {3, 5 / 2}.Like the convex form, it also has 20 equilateral triangle faces, but its vertex figure is a pentagram rather than a pentagon, leading to geometrically intersecting faces. The intersections of the triangles do not represent new edges.
