For a partition λ and a prime p,we prove a necessary and sufficient condition for there to exist a composition δ such that δ can be obtained from λ after rearrangement and no partial sums of δ are divisible by p.To demonstrate why we are interested in the question,we compute some signed p-Kostka numbers.
