Abstract: P-sets（Packet sets） is a pair of sets composed of internal P-set（internal Packet set） and outer P-set（outer Packet set）, which has dynamic characteristics. Based on outer P-set, some concepts related to outer P-set are proposed, such as assistant set of outer P-set, τ-generation of assistant set of outer P-set, τ-strong generation of assistant set of outer P-set, and so on. Furthermore, the relationships among them are discussed. And their relation theorems, identified theorems, unidentified theorems and generation theorems of assistant set of outer P-set are obtained. The theory of P-sets is supplemented.

Key words: outer P-set, assistant set of outer P-set, τ-generation of assistant set of outer P-set, τ-strong generation of assistant set of outer P-set, identification theorems
