The RCWA Package provides methods for computations with the so-called Residue Class-Wise Affine mappings (rcwa mappings for short) and the groups generated by bijective mappings of this type. The rcwa mappings are a type of mappings of certain euclidian rings R into themselves. A possible choice is R = Z. The bijective rcwa mappings of R form a proper subgroup of Sym(R). In general, computing with arbitrary mappings from Z into Z is an algorithmically difficult task. The rcwa mappings provide a class of mappings which are accessible to computations. The investigation of rcwa mappings and groups generated by them is the central aim of this package.
