On the Composition of Baianced Incompiete Bidcic Designs
نویسنده
چکیده
Some inequalities for the lower bound of the number of constraints in an orthogonal array of strength two are derived. A method of constructing balanced incomplete block designs is given which depends upon the existence of two such designs with the same block size. A large number of these designs with k c 4,5 and ~l are also given. Qualified requestors may obtain copies of this report from the ASTIAginia. Department of Defense contractors must be established for ASTIA services, or have their "need-to-know" certified by the cogni-zant military agency of their project or contract.
