The library gitfan.lib for the computer algebra system Singular computes GIT-fans, torus orbits and GKZ-fans. A version without the use of symmetry groups is contained in the current Singular distribution. The symmetric version of the library will first be available in the Singular Source Code Github repository. Since the library relies on changes in the Singular kernel, you will have to compile Singular from the sources. The library will be contained in the next binary release of Singular.
