Query: Reconstructing triangulations of 3-manifolds from their intersection
  matrix   The intersection matrix of a simplicial complex has entries equal to the rank
of the intersection of its facets. In [1] the authors prove the intersection
matrix is enough to determine a triangulation of a surface up to isomorphism.
In this work we show the intersection matrix is enough to determine the
triangulation of a 3-manifold up to isomorphism.
