As you know regular flexagons of order 3n are made from straight strips of paper that contain 9n triangles. When my students helped me count the one of order...
Scott, these are really fantastic as is your site and the new flexagons on your site. A flex you call the pinch pivot looks like what Pedersen and Hilton call...
Thanks Ann. I think I'm going to have to get that Pedersen and Hilton book - you've mentioned several interesting items from it. What type of flexagon does...
I've posted a video of some of the flexes you can perform on a hexaflexagon at http://www.youtube.com/watch?v=tGQ_I4_N3sE. I picked a 5-sided hexaflexagon...
On BUILD YOUR OWN POLYHEDRA: Some other members of this user group have reported that the book is very hard to find now; I think it is out of print. I did,...
I posted a hexaflexagon with face patterns from Sangaku Japanese Temple Geometry problems. You can find this on the right column of the www.flexagon.,net home...
Fascinating video! When I first read about the v-flex and tried to figure it out from text descriptions found on the Internet, I almost gave up. Scot's video...
Ann I've ordered a copy of 'Homage to a Pied Puzzler' and look forward to reading your chapter, and seeing how your analysis compares with some of my findings....
... I am trying to construct the five-faced braided hexaflexagon but am having some trouble understanding the diagram. Part of the difficulty is that some of...
Ah, it looks like I forgot to mention on that page that you'll get a large version of the strip if you click on the small picture. The numbers should be very...
Yes, it's surprising how complex even simple paper folding is. In one of Martin Gardner's columns, he discussed postage stamp folding. Start with a line of n...
Hello all! I've been trying to create a Tetra Tetraflexagon model in excel so I can use it in my technology class with 1st grades, but I haven't succeeded....
Ann Schwartz had talked about being able to view one face six different ways on the nonahexaflexagon. We have decided to use the dodecahexaflexagon as a ...
It's also interesting to note that the simplest hexaflexagon that shows this behavior is the 7-sided braid - http://www.loki3.com/flex/braids.html. In a...
Scott Sherman has, rightly, pointed out in Posting 512 that point flexagons are not particularly photogenic. This can be remedied by using a different method...
That definitely helps. Giving thickness to the faces, making them a solid color and having holes in the faces all help make the structure more visible. And...
The type of cord used to assemble point flexagons made from Meccano plastic sheets is critical. Ordinary string is too thick, too stiff, and doesn't knot...
May your holidays be merry and bright...and like Les Pook's, decorated with a flexagon or two. Our group is now 97 members strong; I'm sure that we'll be break...
Since New Years is a good time for idealism, I figured I would post some theoretical musings. Consider the series of hexaflexagons made from straight strips of...
Hi everybody, My name is Yaacov Belenky, I live in Israel, and I just found the Flexagon_Lovers group. More than 30 years ago, when I was about 16-18 years...
Welcome Yaacov, Interesting work. We've had a few conjectures on which flexes are sufficient for exploring a flexagon, but no proofs. I like how you use the...
Ann, The subject of my original message should be of course, "Several hexaflexagon related theorems and conjectures", not flexaflexagon. If you as a moderator...
... Unfortunately, there is no way (that I know) to edit a message and/or subject line once it is posted. What I can do, is totally remove entire messagew. So...
Yaacov, In the video of the 5-sided hexaflexagon, I show a slot flex that takes you to a singular state, i.e. you can't do a pinch flex or v-flex from that...
I have followed recent postings on transformations between apparently distinct types of flexagons, that can be folded from the same net, with considerable...
A great new product with potential. This article may be of interest to some of you. http://snipr.com/a66i6 Kathy Knapp, Peoria, Illinois, USA Do well your...
Les, I hope to upload an article with proofs on my theorems in a week or two. Regarding the article in Russian: First of all, it is a continuation of a series...
