Although this initially seems to present a challenge for screening low-sodium configurations, it actually does not impact the prescreening process, as these structures have fewer possible configurations. Consequently, all potential sodium orderings are generated, and all symmetrically unique configurations are included in the analysis. The value of prescreening becomes especially evident when approaching the threshold of 60 symmetrically unique configurations, at which it starts to become computationally expensive to include all possible configurations in the DFT calculations. At this stage, where it is crucial to ensure that the lowest energy configuration is included, the Ewald summation method is most accurate. Although there is a minimal risk of excluding critical configurations, the computational resource savings offered by the prescreening justify the trade-off.
