A permutation pattern class package
Version 2.4.3
Released 2022-10-17
This project is maintained by Ruth Hoffmann
The PatternClass package is build on the idea of token passing networks building permutation pattern classes. Those classes are best determined by their basis. Both sets can be encoded by rank encoding their permutations. Each, the class and its basis, in their encoded form build a rational language. Rational languages can be easily computed by using automata, which also can be build directly from the token passing networks. Both ways will build the same language, i.e. the same automaton.
The current version of this package is version 2.4.3, released on 2022-10-17. For more information, please refer to the package manual. There is also a README file.
