Since present code never actually uses a symmetry of defined metrics I propose to drop such an assumption from anywhere.
Ok, but this would cause any metric tensors arising from contractions etc. to have no (specified) symmetry, thereby possibly preventing simplifications if the metric was in fact symmetric. Maybe GiNaC needs to also store the symmetry of the metric somewhere. Bye, Christian -- / Physics is an algorithm \/ http://www.uni-mainz.de/~bauec002/
