Lizzy, I bet you were impressed. They are so cool. My brother showed me, then I showed my kids.#13: CB Paul (cbpaul) on Dec 21, 2019
This was a challenging and fun solve. Thank you! And as a math nerd from way back, I'm so surprized I've never heard of these. I'll look into them.#14: Velma Warren (Shiro) on Dec 21, 2019
Very hard and yet very doable with time. No guessing. Beautiful. I am very anxious to try my own hexaflexagons. Really enjoyed the history lesson also.#15: Teresa K (fasstar) on Dec 22, 2019
CB and Velma, thanks so much! These really are fun to play with. When you fold, be very precise. Enjoy!#16: Brian Bellis (mootpoint) on Dec 23, 2019
I used to have some 3d tetra-hexaflexagons in my classroom but alas...#17: BlackCat (BlackCat) on Apr 12, 2020
Very nice design. Very tough. No guessing.#18: Julio Parra (Julio Parra) on Jun 20, 2020
Preciosa imagen, puzzle duro de resolver, y curiosa aplicación que habrá que estudiar.#19: Teresa K (fasstar) on Jun 20, 2020
Gracias Julio. Este es un objeto muy fascinante.#20: Koreen (mom24plus) on Jan 31, 2021
