A collection of open balls of
radius r can be packed in the unit ball U of a Banach space provided each
ball is a subset of U and the intersection of any two is empty. In an infinite
dimensional Banach space, it is possible to find a largest number Λ so that if
r ≦ Λ then an infinite number of spheres of radius r can be packed in U. In
this paper, upper and lower bounds are found for this number in Orlicz
spaces.
