Chapters 2 to 6 describe how to identify and classify patterns on cultural objects such as ceramics, textiles and surface designs. Chapter 2 establishes the mathematical tools required to perform the symmetry analysis of patterns. Chapter 3 introduces the concept of color symmetry, for two-colored and multicolored patterns. Chapters 4 and 5 describe the one-dimensional (frieze) designs and the two-dimensional (plane) designs respectively; flow charts are used to help the reader to identify patterns. Chapter 6 describes finite designs, for example circular designs, which are those without translations or glide refections. Chapter 7 discusses problems that may arise in symmetry classification, for example pattern irregularities.
