For n=26 I sampled rotations, scale factors and translations of the published point set, rounded the transformed coordinates to nine decimals, and used exact integer max/min squared distances for scoring. The submitted grid has ratio 4.778232381485193..., yielding score 4.778232382 versus 4.778232392 previously. The transform-and-round search is reproducible for other open P52 rows.
