This page is a annotated bibliography on 3 subjects: symmetry, plane tiling theory, plane pattern theory. Symmetry is the mathematical study of symmetry; this usually means group theory with geometry as focus. Tiling theory concerns tilings in the plane. (⁖ what tiles can tile a plane). Pattern theory concerns the classification of geometric patterns in the plane (⁖ pattern classifications, weavings, quasi-periodic patterns). The three subjects are related, but distinct. Among these are also aspects of computational geometry problems related to algorithms that plot patterns or weavings, or solve tiling problems. This is not a comprehensive list, but is fairly complete as a starting point for anyone interested in these subjects.

The majority of references cited here are accessible by undergraduate math majors. A large number of websites are at the level of high school students or nonprofessionals. Others are for mathematicians.

Both printed and web resources are included. It is worth noting that in general, the quality of printed publications are far superior than web resources. In particular, web resources lack depth and accuracy.

This bibliography is roughly grouped into the following 4 sections (click to jump to the section):

This bibliography contains over 30 titles. It may be overwhelming for beginning students. The following paragraphs will give a introduction to the literature for beginners.

An elementary understanding of group theory is either essential or extremely desirable to the study of symmetry or tilings or patterns. Thus, the first thing for serious students is to learn some group theory. If you are not that serious or do not wish to take a systematic learning approach, then you can visit some of the non-technical websites to get a feeling of the subjects first. When you starts to get the feeling that all the talk about symmetry, isometry…etc. are confusing and you are not getting a coherent picture, then it may be time for you to take the following advice.

Group theory is extremely abstract, and is usually taught in the 3rd year college to math majors. However, group theory itself doesn't have any prerequisites in the usual sense. It can be taught to grade level students. What you need is a curious mind and a strong desire to learn. It is often difficult to learn such abstract theory without a teacher. Because its advanced nature, there are very few books that introduce group theory to non-professionals. One of them is Groups and their Graphs amazon by Israel Grossman and Wilhelm Magnus. (1964) Another title you should read is sections 9 to 11 of Geometry and the Imagination amazon by David Hilbert and S. Cohn-vossen. (1932) Both books take a informal approach at high school level, and both are classics. It is by these two books that I (Xah Lee) learned group theory on my own. Once you've grasped the concepts of group theory, then you have many choices of where to go. You can get a deeper and formal understanding of group theory with emphasis to geometry, or you can start learning tiling theory or patterns theory.

There are too many books on group theory, since it is a very important and large topic in mathematics. You might start with a undergraduate exposition by yours truely at The Discontinuous Groups of Rotation and Translation in the Plane. This exposition ties some aspects of group theory and geometry in the plane. If your main interest is in tilings or patterns, then you should buy a copy of Tiling and Patterns amazon by B. Grunbaum and G. C. Shephard. This is the most significant book on this subject by far. It is a standard reference as of 2002, and probably will remain so for many years.

Pattern
A 6-page commentary on a special form of decorative pattern pioneered by architect William S. Huff. The boundary of the pattern are long rectangular shaped (a long strip), and the pattern gradually transforms from one end to the other. The most famous example is artist M. C. Escher's Metamorhposis III. Huff's patterns are purely geometrical. The article includes 13 examples of such patterns with comments by the author on some of them. The author also touchs on the possibility of formalization of creativity. I have scanned these articles.

Tiling and Patterns amazon
B. Grunbaum, G. C. Shephard
Freeman
1987
Tiling, Pattern
This is a comprehensive monograph on all mathematical aspects of tilings and patterns of the plane, treated in a systematic fashion. (However, it does not discuss groups.) The math here is rigorous, but is lively written and accessible to undergraduate. Half of the book comprise well-done illustrations. For example, in this book you'll find a database of tilings and patterns by various classifications schemes, all illustrated. This is a standard reference on the topic, and no other book approaches its scope or depth. This will probably remain so a few years after 2000. Prerequisite: To fully appreciate the book, one must be familiar with group theory and have math maturity of that level. Anyone can also benefit from the book by its vast illustrations. Some sections are suitable for nonprofessionals.

A 10 page article, about 4 pages are photos and illustrations. This article is non-mathematical. It look at traditional Moorish patterns through mathematics. For example, it discusses what symmetry patterns are found, how to analize them mathematically, and problems in analyzing them with symmetry. This is a good article. Prerequisite: group theory.

undergraduate
A 9 page article, about 4 pages are illustrations. This article is mathematical. It gives a non-trivial theory in dealing with counting the number of strands (threads) and crossings in traditional Islamic/Moorish patterns. (decorative weavings) This is a must read for anyone interested in mathematical analysis of Islamic/Moorish patterns. Excellent. Prerequisite: group theory.
