gap-simpcomp

simpcomp is a GAP package for working with simplicial complexes. It
allows the computation of many properties of simplicial complexes
(such as the f-, g- and h-vecors, the face lattice, the automorphism
group, (co-)homology with explicit basis computation, intersection
form, etc.) and provides the user with functions to compute new
complexes from old (simplex links and stars, connected sums,
cartesian products, handle additions, bistellar flips, etc.).
Furthermore, it comes with an extensive library of known
triangulations of manifolds and provides the user with the
possibility to create own complex libraries. simpcomp caches computed
properties of a simplicial complex, thus avoiding unnecessary
computations, internally handles the vertex labeling of the complexes
and insures the consistency of a simplicial complex throughout all
operations.
