Source sentences:
text: The Schönhardt polyhedron is formed by removing the three longest connecting edges, and replacing them by the three diagonals of the convex hull.
text: Alternatively, the Schönhardt polyhedron can be formed by removing three disjoint tetrahedra from this convex hull: each of the removed tetrahedra is the convex hull of four vertices from the two triangles, two from each triangle.
