Abstract
Alon [1] proved that if \(p\) is an odd prime, \(1\le n < p\) and \(a_1,\ldots,a_n\) are distinct elements in \(Z_p\) and \(b_1,\ldots,b_n\) are arbitrary elements in \(Z_p\) then there exists a permutation of \(\sigma\) of the indices \(1,\ldots,n\) such that the elements \(a_1+b_{\sigma(1)},\ldots,a_n+b_{\sigma(n)}\) are distinct. In this paper we present a multiset variant of this result.
