Throughout this paper we work in the category c~ of simply connected, finite CW complexes.Let p be a prime or zero. Denote Zp= Z/pZ for pr 0 and Z o= Q. A space X is p-equivalent to a space Y if there exists a map f: X~ Y such that f induces isomorphisms: H*(Y; Zp)~ H*(X; Zp). Then f is called a p-equivalence. It is not known if p-equivalence is an equivalence relation, in particular, if it satisfies symmetricity. Let us recall that a space K is called p-universal [6] if, for any given p-equivalence k: X~ Y and for an arbitrary map g: K~ Y, there is a map h: K~ X and there is a p-equivalence f: K--+ K such that the following diagram commutes up to homotopy:
