<A HREF=r37_0382.html>groebner</A> basis in any <em>term order</em> 
(which must be the current <em>term order</em>) with the specified

<em>Gindependent_sets</em>computes the maximal 
left independent variable sets of the ideal, that are 
the variable sets which play the role of free parameters in the 
current ideal basis. Each set is a list which is a subset of the 
variable list. The result is a list of these sets. For an 
ideal with dimension zero the list is empty. 
The Kredel-Weispfenning algorithm is used.
