For q, an odd prime power, we construct symmetric 2q 2 2q 1Y q 2 Y 1 2 qq ร 1 designs having an automorphism group of order q that ยฎxes 2q 1 points. The construction indicates that for each q the number of such designs that are pairwise non-isomorphic is very large.

To Haim Hanani on the occasion of his 75th birthday. Let D be a block design which has a blocking set. We call D self-blocking if the following two conditions hold: (i) The committees of D (i.e. the blocking sets of minimum cardinality of D) form a block design, which we denote by DC and (ii) The co
