Reviews

' ... an excellent resource for anyone with little previous knowledge to understand the basics, but with enough detail to satisfy the interest of all but the most ardent mathmos.' Eureka 'Pook's book summarizes a great deal of what is known about flexagons of all shapes and types, and contains much new material ... an excellent purchase for someone who already knows something about flexagons and wants to know more.' Ethan Berkove, Lafayette College 'This interesting book contains a wide collection of nets for making paper models of flexagons.' Zentralblatt MATH 'This book would be an excellent purchase for someone who already knows something about flexagons and wants to know more.' Society for Industrial and Applied Mathematics 'The main advantage of the book is that it gives a mathematical analysis of flexagons by using only elementary mathematical concepts. Thus this book will be very useful for anybody who is not a professional mathematician but wants to get some insight into the mathematical structure of these exciting puzzles.' EMS Newsletter '... a thorough comprehensible work ... keeps the text readable and easy to follow. ... This book would be appropriate for anyone at the undergraduate level or higher, and would likely be enjoyed by anyone with an interest in recreational mathematics.' Mathematical Association of America Online
