13. If the ordering of Cu and Fe were critical for the CMR properties, then the phenomena displayed would be unique for the compositions with 1:1 Fe/Cu ratios. Existing evidence contradicts this.
14. This arrangement is not unique but is degenerate over many symmetry equivalent combinations in the cubic unit cell.
