| ##### 7.5.4.0. reiffen Procedure from library `dmod.lib` (see dmod_lib). Usage: reiffen(p, q); int p, int q Return: ring Purpose: set up the polynomial, describing a Reiffen curve Note: activate the output ring with the `setring` command and find the curve as a polynomial RC. A Reiffen curve is defined as RC = x^p + y^q + xy^{q-1}, q >= p+1 >= 5 Example:
    LIB "dmod.lib";
    def r = reiffen(4,5);
    setring r;
    RC;
    ==> xy4+y5+x4
