       nroots
           Number of generator roots = number of parity symbols

       fcr
           First consecutive root, index form

       prim
           Primitive element, index form

       iprim
           prim-th root of 1, index form

       gfpoly
           The primitive generator polynominal

       gffunc
           Function to generate the field, if non-canonical representation
