We study P systems with symport/antiport and a new model of purely catalytic P systems, called purely multi-catalytic P systems, when these devices use only one symbol. Our proofs use unique-sum sets, sets of integer numbers whose sum can only be obtained in a unique way with the elements of the set itself. We improve some results related to the descriptional complexity of the P systems with symport/antiport considered by us and we define one infinite hierarchy of computations.
