Book recommendations for Combinatorial Designs I am well-acquainted to basic topics of experimental designs such as anova, ancova, crd, rbd, lsd, factorial design, robust design etc (as per the book of Dr. D. C. Montgomery). Now as per my recent ongoing research curriculum, I need to learn more mathematically oriented combinatorial design. The topics I need to learn are finite geometry, steiner systems, t-designs, resolvable designs, pairwise balanced design, directed design, pbd, tuscan squares, vector space design, packing, partial geometry, sequences with zero autocorrelation, D-optimal design etc and some other topics based on abstract and linear algebra. I have started with the book by W. D. Wallis but not all topics (such as equidistant permutation array, skolem sequences and many other topics aforementioned) are covered in this book. Also Wikipedia gives a list of references but I am not sure which one to pick beside the book I am using.
Would you kindly like to recommend books on combinatorial design that cover these topics? All suggestions and recommendations are valuable and appreciated.

There is a book on the topic which actually have its own page on wikipedia!.  Start with that one.  amazon link
Also Introduction to Combinatorial Designs (Discrete Mathematics and Its Applications) 2nd Edición  by W.D. Wallis, with empasis on the maths, but ending with statistical applications.
