[King of Nets] Polyhedron (See the New Pit with the Same Name)

I held my nose and read the original manuscript of 2019. I can feel that I was working hard to write it, but I was still crazy about it... Rewrite, must rewrite! Although the wording of the copy is somewhat mediocre, it's still okay, so I'll keep it for now… I originally wanted to rewrite it in the old pit, but I tried it and found that I couldn't save the manuscript after editing it directly. I was confused. I'll see you in the new pit with the same name. Intention: None
