- ascotan 6y agoIs flexagon a made up word? Come on.
- detaro 6y agoIt's an established mathematical term for these things. Of course, mathematical terms tend to be "made up" at some point, but I don't think that's a useful distinction.
- rjsw 6y agoHave you never read any Martin Gardner books ? The wikipedia page [1] on the things is a good introduction too. [1] https://en.wikipedia.org/wiki/Flexagon https://en.wikipedia.org/wiki/Flexagon
- Pfhreak 6y agoIt's going to blow your mind when you realize all words are made up. Even more so when you find out that definitions change and new words are invented every year.

- timpark 6y agoI made some tetra-tetra-flexagons for my wedding, and in the process made an ImageMagick script to take four images and turn them into two, one for each side of the sheet of paper. https://www.timpark.org/making-a-tetratetraflexagon/ https://www.timpark.org/making-a-tetratetraflexagon/ (unfortunately some of the external links are broken, I should do some editing)

- ScottBurson 6y agoI still have a 24-faced hexaflexagon I made in 1975, using onionskin paper and an HP plotter. (Thinness and accuracy are critical for high-order flexagons.)
