This book presents interesting applications of abstract algebra to practical real-world problems. The book is appropriate as either a text for an applied abstract algebra course or as a supplemental text for a standard course in abstract algebra. While fully developed, the algebraic theory presented is just what is required for the applications discussed in the book.

3. BALANCED INCOMPLETE BLOCK DESIGNS
4. ALGEBRAIC CRYPTOGRAPHY
5. CODING THEORY
6. SYMMETRY GROUPS AND COLOR PATTERNS
7. WALLPAPER PATTERN GROUPS
