We show that there exists a lattice covering of ℝn by Eucledian spheres of equal radius with density O(n lnβ n ) as n→∞, where β:= (1)/(2) log2 ((8 πe)/(3√ 3))=1.85837... . This improves upon the previously best known upper bound by Rogers from 1959 of O(n lnα n ), where α:= (1)/(2) log2(2πe)=2.0471... .
