We discuss the symmetries of the configuration space for homogeneously disordered binary alloys and argue that these symmetries must be maintained in any meaningful approximation if the results are to be physically significant.

We had earlier presented a computationally feasible and fast technique for obtaining the electronic structure of random alloys which allowed us to incorporate short-ranged order and effects like clustering and local lattice distortions due to size mismatch effects. The technique combined the augmented space recursion with the tight-binding LMTO. We have recast the formalism in a way that allows us to sample many more configurations states and bring the basic equations in a one-to-one correspondence with the screed KKR formalism.
