Topological Software (in GAP)

• BISTELLAR (Version Nov/2003): heuristics to reduce the size of a given triangulated manifold; it can be used to recognize combinatorial d-spheres and therefore to test whether a pure simplicial complex is a combinatorial manifold.

• BISTELLAR_EQUIVALENT (Version Feb/1999)

• FundamentalGroup (Version Nov/2003): routine to compute a ``small´´ presentation of the fundamental group of a finite simplicial complex.

• MANIFOLD_VT (Version Apr/2002)

• SEIFERT (Version Nov/2003): produces triangulations of all Seifert manifolds.

• DiscreteMorse (Version May/2015): searches for discrete Morse vectors with few critical cells.
