Currently same_metric replaces the indices with indices from the metric of another clifford object (assuming that they are present). CD> indexed(metric, i, j). Is the purpose of having the metric CD> inside an indexed object to also store the symmetry of the CD> metric? Yes, this is another important reason which I forgot to mention. Besides that the presence of indeces keep record on the dimensionality of the Clifford algebra. Otherwise it need to be stored separately if the metric is given for example by minkmetric. Overall keeping metric as indexed object can provide some important info on generic Clifford algebra which otherwise would be lost. Best wishes, Vladimir -- Vladimir V.
