Discussion Overview

This thread involves participants describing increasingly large natural numbers using established mathematical notation. The focus is on creativity and interest in the way numbers are presented, rather than simply stating larger values.

Discussion Character

  • Exploratory
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant initiates the game by stating the number 1.
  • Another participant proposes the number 2.
  • A participant describes the number ##(1+i)^8##, which equals 16, and discusses the notation involving the imaginary unit i.
  • There is a discussion about the nature of complex numbers and their relation to the proposed number.
  • A participant introduces the number ##F_2 = 2^{2^2}+1##.
  • Another participant claims the largest number they can write is 18.
  • A participant mentions 18 squared, which leads to a historical reference about cricket.
  • There are multiple references to the year 1930 and discussions about its significance.
  • A participant proposes the number 5692 from the Hebrew calendar, while another suggests 5691 squared as a larger number.
  • Discussions arise about the validity of using expressions like ##i^i## and the need for specific definitions of "large enough" in mathematical terms.
  • One participant retracts their entry, while another proposes the classic number 1729.
  • A participant discusses the properties of triangle numbers and proposes the binomial coefficient ##\binom{2^{13}}{2^{12}}## as a large number, providing a lengthy numerical value for it.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the largest number, as multiple competing views and expressions are presented throughout the discussion.

Contextual Notes

Participants express uncertainty regarding the definitions and conditions for what constitutes a valid larger number, particularly in the context of complex numbers and the phrase "large enough."

Graham's number
Doesn't count unless you express it in established mathematical notation.

Oof so we're already going there. It's going to get tough from now on.

Okay, TREE(3).

Remember the rule! I know it is a known mathematical number but the point of the thread is to be able to write it down using common mathematical notation. Unless someone already knows about that tiny tiny area of math in particular they're not going to know what a TREE(3) is.

I think this would have been more interesting to the non-mathematicians if, for each new number, the poster had to tell us the number of digits in the (base 10) representation. Remember, this thread is in General Discussion.

The number of digits in Graham's number, for instance, is nearly as staggering as the number itself and is best written as log(Graham's number).

Wikipedia said:
But even the number of digits in this digital representation of Graham's number would itself be a number so large that its digital representation cannot be represented in the observable universe. Nor even can the number of digits of that number—and so forth, for a number of times far exceeding the total number of Planck volumes in the observable universe.

It's freaking big.

How about googolplex? A googol ##=10^{100}##, googolplex ##=10^{googol}##.

This is starting to degenerate to the form ##X_{n+1} = X_n + K ## for some ##K##.

I originally made the thread in the General math section but it was moved here.

Anyways, we're still at Graham's number, and I have some ideas to get some number that is significantly larger but I want to see what other people have.

That's way smaller.

Rayo's Number = Rayo(10^100) where Rayo(n) is uncomputable :P

Ignoring the game and just listing an interesting big number

25^1312000 is ‘Borges’ number’ - the number of books in the Library of Babel
