Let P = PG(2t + 1, q) denote the projective space of order q and of dimension 2t + 1 ~> 3. A set Β£f of lines of P is called a blockade if it fulfills the following two conditions. 1. Every (t + 1)-dimensional subspace of P contains at least one line of ~o. 2. Ifx is the intersecting point of two lin
