Assertion: tesseract's vertex | /r/HasProperty | connected to bottom vertex map
Facets:
value: to the simplex's vertices
type: TRANSITIVE-OBJECT
Source sentences:
text: Each vertex connected to the top vertex then uniquely maps to one of the (n-1)-simplex's facets (n-2 faces), and each vertex connected to those vertices maps to one of the simplex's n-3 faces, and so forth, and the vertices connected to the bottom vertex map to the simplex's vertices.
