Individual simplices in a simplicial complex can be completely separate or stuck together by sharing a face, an edge, or a vertex. Crucially, the intersection must happen along an entire face, never just a partial face.

Conditions: The object is a simplicial complex.; Intersections occur between any two simplices within the complex.
