Using letters, symbols and numbers write the largest number you can in 100 characters or fewer.

No infinity/s and if you make up a symbol/operation/etc you must be able to define it with in the 200 characters.

I'll start with a relatively small number to get the ball rolling.

A pointless challenge, since each successive post can outdo the previous post with the following:

"The sum of every natural number smaller than the number >>3342 posted"

(replace post number as appropriate).

It's short and guaranteed to be larger.

you can use Knuth's up-arrow notation though; >>3349

ε₀ = ω^^ω


 No.3403

>>3401

>>3400

ε0 is the upper limit of the largest countable ordinal. You can reach it with knuth's notation, but ultimately ε0 is what is reached before you get to uncountable ordinals.

>>3400

>>3396

woah woah woah.. you can't use infinite ordinals because infinities are not allowed, especially not on their own as that's just (an) infinite. you might be able to get away with using it to construct a function from the fast growing hierarchy, as that would out-put a finite number but you'd still be using the properties of an infinite to get it, so i don't know if that would still be against the rules.

x

x is defined as largest number less than infinity


 No.3428

would "the sum of all numbers" count as an infinity?

I can prove that your numbers don't exist as their existence would cause a paradox


 No.3444

>>3430

doit faggot


 No.3448

>>3444

okay

>>3427

your number plus one cannot exist

the relation "being bigger" is defined through plus one operation

therefore your number isn't a natural number as you can always add one to a natural number

>>3428

similar to >>3428 except that here I try to define sum of all numbers plus itself


 No.3462

ok how is this: the sum of all numbers except for that sum itself

 No.3465

>>3462

yeah no

every natural number n has it's successor, n+1.

the sum of all numbers except for that sum itself plus one is greater than the sum of all numbers except for that sum itself, but it's not that sum itself, therefore it must be included in the sum.

but, the sum of all numbers except for that sum itself is lesser than the sum of all numbers except for that sum itself plus one, therefore it cannot include the sum of all numbers except for that sum itself plus one in the sum, which is a paradox.

therefore the sum of all numbers except for that sum itself, if it exists, isn't a natural number.


 No.3480

>>3465

>therefore the sum of all numbers except for that sum itself, if it exists, isn't a natural number

OP didnt say it has to be a natural number


 No.3481

>>3352

I'm changing the symbol to this:

🍆


 No.3483

>>3480

okay so I have to get to a contradiction

so in >>3465 I proved that your number cannot be a natural number. however, a sum of natural numbers is always a natural number (since you can break summation down into iterated successor relation, which is the relation that defines natural numbers as a set).

so we can see that your number is a natural number, yet cannot be a natural number, therefore your number cannot exist.
