You can also still send in a polyhedron from anywhere in the world or enquire about hosting it yourself. https://polyplane.org/ Polyplane is made possible thanks to fiscal sponsorship from the Seattle Universal Math Museum. https://seattlemathmuseum.org/ Thanks to Henry Segerman for helping out as well. You should watch their awesome videos: https://www.youtube.com/@henryseg Huge thanks to my PatreonPlane supporters. They covered the "press pass" I had to buy to access the Joint Math Meeting. I could as part of the Press, right? https://www.patreon.com/standupmaths CORRECTIONS - None yet, let me know if you spot anything!
