A GAP package to deal with numerical semigroups and affine semigroups
This notebook features Mathematica functions for working with and visualizing C-semigroups in N², using the Normaliz package. Normaliz is an open-source tool for computations in affine monoids, lattice polytopes, and rational cones (https://www.normaliz.uni-osnabrueck.de/).
