Solution of the Littlewood-Offord problem in high dimensions

Consider the 2' partial sums of arbitrary n vectors of length at least one in d-dimensional Euclidean space. It is shown that as n goes to infinity no closed ball of diameter A contains more than ([A] + 1 + o(l))(ln2I) out of these sums and this is best possible. For A - [A] small an exact formula is given.
