We complete the proof of the upper bound \({\hat{\rho }}_3\le 10R\) for the regularity radius of Delone sets in three-dimensional Euclidean space. Namely, summing up the results obtained earlier, and adding the missing cases, we show that if all \(10R\)-clusters of a Delone set X in \({\mathbb {R}}^3\) with parameters (rR) are equivalent, then X is regular (has a transitive symmetry group).

关于$$ {\ mathbb {R}} ^ 3 $$ R 3中的Delone集的规则半径

我们完成了三维欧氏空间中Delone集规则半径的上限\({{hat {\ rho}} _ 3 \ le 10R \)的证明。即,总结先前获得的结果,并添加缺失的案例,我们表明,如果Delone的所有\(10R \) -集群在参数(r\ r {\ mathbb {R}} ^ 3 \)中设置X,  R)是等价的,则X是规则的(具有传递对称组)。
