【 摘 要 】

We consider the higher-order Fierz transformation, which corresponds to expanding a product of <()over bar>Gamma psi terms into a sum of products of Dirac densities and currents. It is shown that the Fierz transformation can be obtained by solving a large system of linear equations with fractional complex coefficients, which is practical at least up to fourth power.
