That quote is of course one of Piet Hein's most famous "Grooks": Problems worthy of attack Prove their worth by hitting back - just Google "Piet Hein" Neil...
... I love that book and the notion of living out of a suitcase and needing only your brain for a toolkit. But that little poem is one of Piet Hein's 'Grooks'....
Ann's first question is how did I think of compound flexagons. The answer is that the basic idea came from Chapter 13 of Conrad and Hartline. They provide...
Well, the compound flexagons are an incredible achievement. I recommend all "flexers" to venture beyond the variations of the hexaflexagon (wonderful though it...
Thanks for taking the time to build one. The traverse shows the quickest way to see all faces. Your way could be more fun. Going through the traverse means 'do...
Well, I THOUGHT I could do the traverse with my eyes closed... When you do the traverse, do the "subdominate faces" (to borrow a term from music)--the violet,...
T. B. McLean, "V-Flexing the Hexahexaflexagon," The American Mathematical Monthly, 86, pp. 457-466, 1979. is available on http://www.jstor.org/ if your school...
Thanks. I added your article to the Links section of this site, for those of us who have access to Jstor. (luckily, I'm only a few blocks away from the science...
I am new to this group and have only recently discovered its existence. Flexagons have been an interest to me for as long as I can remember. Glancing through...
Nice flexagon site! I like the fact that you include templates for the often ignored tetrahexaflexagon and the pentahexaflexagon. You might want to check out...
I have many flexagon patterns cluttering up my hard disk, but not in very user friendly formats with directions. By creating the flexagon.net website, my...
Like many people on this group, my introduction to flexagons was from Martin Gardner. I had played around with them long ago, but recently I was trying some...
Scott Nice to see your posting on point flexagons, which are a new family of flexagons. I've made up all your examples, but had a slight problem with the one...
Thanks for the catch, Les. I fixed the link so you should be able to get the correct net now. And also thanks for Flexagons Inside Out. I've had a lot of...
Scott, I can now get the correct net, I'm glad you like Flexagons Inside Out. I had a lot of fun writing it. The reason why the point flexagon version of the...
Recently I was wondering if you could fold the same strip different ways to create flexagons with different behavior. I found that the answer is yes. Has...
I have had a look through my collection of hexaflaexagons, and the smallest number of faces for which alternate numberings of a net are possible is 7. This of...
I am way behind, only just lately got thru to this group, after trying a long time. So some ideas may be funny. I have the math counting theory down pretty...
I just tried the skeletal hexahexaflexagon. No wonder you used paper clips. But it flexes in interesting ways. I set it on a table in a hexagonal star...
"skeletal hexahexaflexagon" - I like that. I've also tried some point flexagons that look more like normal flexagons and aren't simply stacks of pats and it...
I found the articles by Ann Schwartz on the 12-gon quite interesting. I decided to explore the "Junior" members of this flexagon family. I found that the...
As a correction to my last post, the Tri-dodecaflexagons also have the "Rogue triangles". They do not play as interesting a role as in the dodecaflexagons...
It¢s interesting that 7 faces is the smallest hexaflexagon that has alternate numberings from the same strip. Square flexagons seem to allow variety much...
Very nice. It's so easy to get lost in the 6 sided version it's useful to have a 3 sided one to play with to learn from. Scott ... From: robin_moseley...
Ok, I will reply to my own question. Actually the various theory articles cover this question for the hexaflexagons. Here is an interesting table: faces...
The correspondence between point and edge flexagons isn¢t as direct as I was expecting. You can¢t necessarily create a single stack point flexagon from an...
The attached interim report on dodecaflexagons summarises the results of my investigations into their dynamic properties. It complemnets some other revent...
Scott I'm not sure how the point square flexagon with face numbering 1/2, 7/6, 3/4, 1/8, 5/6, 3/2, 7/8, 5/4 should be assembled. Can you elucidate please. I'd...
Since it was published in 2003, a few errors have come to light in my book 'Flexagons inside out'. These have either been brought to my attention by fellow...
