| Oct 19, 2014 at 7:17 | comment | added | Federico Poloni | In numerical linear algebra, where transposes normally go on the right, the notation $A^{-T} := (A^{-1})^T = (A^T)^{-1}$ is quite common, and on rare occasions I have seen $A^{2T}$. So there is an analogously suggestive solution even putting transposes on the right. | |
