This volume includes thirty-three papers by eminent mathematicians, statisticians, and electrical engineers. The papers are organized into five main divisions: general problems of combinatorial mathematics; combinatorial problems of experimental designs; error-correcting codes and other problems of information theory; finite geometrics; and graphs. Many of the papers are followed by prepared discussions.<br/><br/>Contents<br/>General Editor's Preface<br/>Preface<br/>Conference Participants<br/><br/>PART I.
