The partition ?J clearly has a diagonal of length r (which is how many

Fr(Ai) = [ q + h - l , . . . , q + i r - l \ h - l , . . . , i r - l ] .

Since ^-s(0 = ^s(0/ we assume without loss of generality that s > 0. When dealing with the CGPF of systems with (p,£^)-statistics, the parameter s will usually stand for p - q. For instance, for p - q > 0 the (p, (j)-envelope

introduced before can be equivalently defined

as the set of all those partitions A for which r,\ (p - q) < q. With this in mind it follows that Lemma 2.7. f4^ = EZ(,(2-82)
