The recent electronic orbital tableau ("jawbone") formulas of Harter and Patterson for matrix representatives of elementary generators of $U\left(n\right)\mathrm{}$ in the canonical basis are shown to be simply related to our expressions for the latter, which are based on a simplified Gelfand tableau formalism pertinent to $N$-electron problems, a brief survey of which is given in a form particularly suitable for computer implementation.
