Comb. Structures Lecture Notes

Lecture Notes

The text is written under the philosophy that by studying particular special cases in detail, enough information is gained to permit the reader to easily generalize the material to the general case. While I am somewhat sympathetic to this point of view, I do feel a need to provide some additional information on the general case. The following table provides some lecture notes that deal with the more general situation keyed to the text.

Chapter	Topic	Supplementary Notes (.pdf files)
1	Steiner Triple Systems (.pdf file)	Latin Squares
2	$\lambda$ -Fold Triple Systems	BIBD's
3	Maximum Packings and Minimum Coverings	?
4	Kirkman Triple Systems	Parallelisms of Designs
5	Mutually Orthogonal Latin Squares	Supplementary Material
6	Affine and Projective Planes	Projective Geometry
7	Steiner Quadruple Systems	t-designs

The following lecture notes do not correspond to the text, rather they are notes from earlier versions of this course and may prove to be useful as alternative treatments of some material. They are available for:
