We study the Mordell-Weil lattices ([9]) of the elliptic $K3$
surfaces which have been introduced by Inose [4] and Kuwata
[6]. The point is that the lattices (of rank up to 18) arising
this way can be of some interest in terms of sphere packings.
In this note, we treat the case of rank 16, 17, or 18, and
show that these Morderll-Weil lattices are potentially comparable
with the record lattices in these dimensions ([2]). The detailed
accont is in preparation, which will include the corresponding
results for other dimensions as well.
