Ipsius Number[]
The Ipsius Number is the number on the border of countable (like Googol) and uncountable numbers (like Infinity). The number is not very well defined, as making a borderline between “countable” and “uncountable” numbers was seen as impossible. The number is a very newly-discovered number from P01du.
The name “Ipsius” originates from the latin word “uncountable” (according to Google Translate).
The number actually has no short equation. Of coirse, I don’t want to write it all here because that would give the page a lot of bytes.
