[GAP Forum] simpcomp

[Ellis, Grahamj]

Dear GAP Forum,

It is my pleasure to announce that the simpcomp package has been accepted as an official GAP package. The package, authored by Felix Effenberger and Jonathan Spreer, is a great addition to GAP's functionality in the area of simplicial complexes. ( https://code.google.com/p/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-vectors, 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 was awarded the "Best Software Presentation Award" by the Fachgruppe Computeralgebra for a presentation given at ISSAC 2010 in Munich, July 26, 2010.
