PerMuVAR -- a MuPAD library for invariants of permutation groups
PerMuVAR was an open source library for the
computer algebra system MuPAD for
computing in invariant rings of permutation groups. The purpose was to
study (at least partially) permutation groups that are too big to be
treated by general invariant theory software. The main design goals
were the following:
PerMuVAR is now integrated in MuPAD-Combinat.
- Computation timepredictability (algorithms based only on linear algebra, no
Gröbner basis computations);
- Reusability and extensibility (object oriented programming);
- Efficiency (Use of special properties of permutation groups;
use of external specialized libraries for critical sections).
