Facets:
Source sentences:
text: Its cells ( 3 -faces) are such that two cells either do not intersect or share a common facet ( 2 -face), edge ( 1 -face) or vertex ( 0 -face).
text: As in the underlying combinatorial triangulation (see Chapter ), edges ( 1 -faces) and facets ( 2 -faces) are not explicitly represented: a facet is given by a cell and an index (the facet i of a cell
