We define a group theoretical invariant, denoted by s G , as a solution of a certain set covering problem and show that it is closely related to chl(G), the cohomology length of a p-group G. By studying s G we improve the known upper bounds for the cohomology length of a p-group and determine chl(G)

In f 1 we introduce the concept of V-semi-identifying lift (V-semi-idt. lift) generalizing our concept of V-idt. lift [8], whose specific properties we want to discuss in another paper, and at the same time generalizing WYLER'S concept of V-proclusion pair [is]. We characterize those functors V : C
