The V-Flex, Triangle Orientation, and Catalan Numbers in Hexaflexagons
Martin Gardner in the Twenty-First Century
(2012)
Abstract
Regular hexaflexagons mysteriously change faces as you pinch flex them. This paper describes a different flex, the V-flex, which allows the hexahexaflexagon (with only 9 faces under the pinch flex) to have 3420 faces. The article goes on to explain the classification of triangle orientations in a hexaflexagon and to give an example of flexagon combinatorics.
