Flexagons are two-dimensional hexagon objects folded from a straight strip of paper. The process of folding and twisting the paper to form the hexagon introduces an extra face into the original, two-sided paper, much in the way a mobius strip is a one-sided object from a two-sided paper.
The first formal study of flexagons is said to have begun in 1939 by a group of graduate students at Princeton. The students did not create formal mathematical models of their topology (the study of the properties of objects and surfaces) but created many different ones, including one with 48 faces. Subsequent researchers have described such models for the flexagons and have shown relationships to other algorithms (step-by-step procedures) and computer programming.
