Facets:
value: to the three-dimensional ball
type: TRANSITIVE-OBJECT
value: for another example
type: OTHER
Source sentences:
text: For another example, any convex polyhedron is homeomorphic to the three-dimensional ball, so its surface is homeomorphic (hence homotopy equivalent) to the two-dimensional sphere, which has Euler characteristic 2.
