Abstract
Five years ago at GMC my daughter helped me present her 8th grade science project on the nonahexaflexagon. A regular flexagon contains 9n equilateral triangles, folded from a straight sheet of paper, and was discovered in 1939 by topologist Arthur Stone. It is a Möbius band with 3(3n-2) half-twists, and the pinch flex moves it to 6n-3 different mathematical faces. The V-flex scrambles the colors like a flat Rubic's cube and we will provide a 2009 algorithm that counts the number of mathematical faces for all n>0.
