Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01The 3D regular convex polyhedrons are super famous, have the name: Platonic solid, and have been known since antiquity. In particular, there are only 5 of them.
The counts per dimension are:
Table 1.
Number of regular polytopes per dimension
. | Dimension | Count |
|---|---|
| 2 | Infinite |
| 3 | 5 |
| 4 | 6 |
| >4 | 3 |
The cool thing is that the 3 that exist in 5+ dimensions are all of one of the three families:Then, the 2 3D missing ones have 4D analogues and the sixth one in 4D does not have a 3D analogue: the 24-cell. Yes, this is the kind of irregular stuff Ciro Santilli lives for.
The Nobel Prize of mathematics!
That 15,000 canadian dollar prize though, what a joke!!

Too "direct formula overload" at first look.

- youtu.be/Goim-4MF_uE?t=965: he drove Szilard to propose to Einstein the Einstein-Szilard letter
Ciro's theory for his disappearance is that he became a Majorana fermion and flew off into the infinite.
