Flexagons

Flexagons are flat models that are usually constructed by folding strips of paper into geometric shapes. They can be "flexed", or folded in certain ways, to reveal hidden faces. They were discovered by Arthur H. Stone and popularized by Martin Gardner.

Equation for finding number of individual polygons on a strip for a flexagon that has a certain amount of faces and a number of polygons in each face:

f*n

Where f is the number of faces and n is the number of polygons on each face.

Re: Flexagons

Hmmmm, interesting. Recreational mathematics has always been a side hobby of mine.
