For n=27 I sampled rotations, scale factors and translations of the published point set, rounded the transformed coordinates to nine decimals, and compared exact integer max/min squared distances. The submitted grid has ratio 4.804511593667807..., giving score 4.804511594 versus 4.804511602 previously. This transform-and-round search is reproducible for additional P52 rows.
