Which hypercube unfoldings tile space? https://whuts.org/
Yes, you can buy one of the 261 models from this video and support the channel. All hand-numbered by me and with a signed certificate of authenticity. https://mathsgear.co.uk/products/cube-model
Here is Giovanna Diaz and Joseph O’Rourke’s paper: https://arxiv.org/abs/1512.02086
A091159 Number of distinct nets for the n-hypercube. https://oeis.org/A091159
The code Moritz used to find these values is here: https://github.com/google-research/google-research/tree/master/cube_unfoldings
All of Moritz Firsching’s 3D models: https://mo271.github.io/mo/198722/unfoldings.html

This is the Math Overflow post which started it all: https://mathoverflow.net/questions/300713/number-of-hypercube-unfoldings
Peter Turney’s 1984 paper Unfolding the Tesseract https://unfolding.apperceptual.com/
The unfolding animation of the ‘Dali cross’ was kindly made by my Patreon supporter John Sawyer.
I actually put the rough-cut of this video out on Patreon earlier this week so they could provide feedback and help test the whuts.org site. Thanks so much for all of your help everyone! https://www.patreon.com/posts/51144440
– I saw "288" at the end of the 8D number when it should be "228". The on-screen number is correct. I noticed too late to fix it!
– At 21:09 I say Diaz and O’Rourke found an unfolding of the Dali cross which tiles the plane. It’s actually a different 3D net they found which does this and the Dali is undetermined if it produces a tiling 2D net. (Thanks Dan L by email.)
– Let me know if you spot any more mistakes!
