A blocking set of a design different from a 2-(ฮป+ 2, ฮป+ 1, ฮป) design has at least 3 points. The aim of this note is to establish which 2-(v, k, ฮป ) designs D with r โฅ 2ฮป may contain a blocking 3-set. The main results are the following. If D contains a blocking 3-set, then D is one of the following d

We present here some new constructions of block designs with repeated blocks for arbitrary k. We include some interesting examples. A partial answer to a question raised by Hedayat is also given.
Under the assumption that the incidence matrix of a 2-(45, 12, 3) design has a certain block structure, we determine completely the number of nonisomorphic designs involved. We discover 1136 such designs with trzvial automorphism group. In addition we analyze all 2-(45, 12, 3) designs having an auto
