If I’m understanding this correctly, the statement is “There is a set of provably true assertions that are held in every n-dimensional geometry, except for n=4”

If so, that’s fascinating. Has there been any proofs around why a dimensional ordinality (if that’s the right term) of 4 is different?
- kevinventullo 5y agoYes, and I agree it is fascinating! As for “why” 4-dimensional geometry is somehow special, I couldn’t tell you, but here’s a whole MO thread about it: https://mathoverflow.net/questions/47569/what-makes-four-dimensions-special https://mathoverflow.net/questions/47569/what-makes-four-dim...
