Discrete

Discrete is a Mathematica package providing tools for model building with discrete symmetries. Its main features are

  • the calculation of arbitrary Kronecker products;
  • an interface to the group catalogues within GAP, e.g. the SmallGroups library with all discrete groups up to order 2000 (with the exception of groups of order 1024) and many more;
  • calculation of Clebsch-Gordan coefficients (They are calculated on demand and are stored internally, in order to improve the performance);
  • the possibility to reduce covariants to a smaller set of independent covariants;
  • the documentation is integrated in the documentation centre of Mathematica.
