`tolexm', `minipolym'
---------------------

tolexm(PLIST,VLIST1,ORDER,VLIST2,MOD)
     :: Groebner basis computation modulo MOD by change of ordering.

minipolym(PLIST,VLIST1,ORDER,POLY,V,MOD)
     :: Minimal polynomial computation modulo MOD the same method as

RETURN
     `tolexm()' : list, `minipolym()' : polynomial

PLIST, VLIST1, VLIST2
     list

ORDER
     number, list or matrix

MOD
     prime

   * An input PLIST must be a Groebner basis modulo MOD with respect to
     the variable order VLIST1 and the order type ORDER.

   * `minipolym()' executes the same computation as in `minipoly'.

   * `tolexm()' computes a lex order Groebner basis modulo MOD with
     respect to the variable order VLIST2, by using FGLM algorithm.
