Hexaflexagon

Select the variant of the hexaflexagon that you want to assemble. Flexagons are flat models made by folding strips of paper, their name derived from the verb ‘to flex??™. The hexaflexagon also did a good job in the popularisation of mathematics. In 1956 the mathematician and science populariser Martin Gardner published an article in the Scientific American magazine in which he published instructions and a template for its construction.
