In fact, SingularValueList[] works on symbolic matrices, but the results are expectedly nightmarishly long in most cases.

You might be able to get something usable from Eigenvalues[Transpose[mat].mat]

Well, if one doesn't check for "negative identities", one gets $t[i], i=1,\ldots,15$, while checking gives us $t[i], i=1,\ldots,13$, certainly a reduction, but apparently not enough of one to make a SingularValueList computation feasible. | |
