The Ultimate Googol is a number i came up with. I decided to create a good large number, so I came up with this.

**Note: **I think this could be part of the great ''googol'' series, so I putted this number in the category.

## Definition

Think it of this way:

0G(0) = googol = 1 followed by 100 zeros.

0G(1) = googolplex = 1 followed by a googol zeros.

0G(2) = googolduplex = 1 followed by a googolplex zeroes.

Then, we can make the following formula:

0G(N) = googol-n-plex = 1 followed by a googol-(n-1)-plex zeroes.

But the series end at 0G(G) or 0G(Googol), so we would continue with 0GG(0)

0GG(0) = 0G(Googol)

0GG(1) = 0G(Googolplex)

0GG(2) = 0G(Googolduplex)

And so on...

And the formula:

0GG(N) = 0G(Googol-n-plex)

And when we ran out of 0GG series numbers, we continue with the 0GGG series numbers:

0GGG(0) = 0GG(Googol)

0GGG(1) = 0GG(Googolplex)

and so on...

And then with 4 G's, and then with 5, 6, 7, 8, 9, 10, etc...

But this G's are too many!

So we make a short name for this:

0G-7(0) = 0GGGGGGG(0) (7 G's!)

And we continue like that adding G's, and adding G's, and so on.

But...

This ends at 0G-Googol(Googol), so we start the 1G Series.

1G(0) = 0G-Googol(Googol)

1G(1) = 0G-Googolplex(Googol)

and so on...

Then, we create a formula:

1G(N) = 0G-Googol-n-plex(Googol)

But we can continue with the 1GG series after we're done with the 1G series.

1GG(0) = 1G(Googol)

1GG(1) = 1G(Googolplex)

and so on...

And when we reach the 1G-Googol(Googol), we start with the 2G series.

2G(0) = 1G-Googol(Googol)

2G(1) = 1G-Googolplex(Googol)

and so on...

And then we continue with the 3G series, the 4G series, and so on...

But what is the GoogolG-Googol(Googol)?

That is called Super Googol.

Then, a (Super Googol)G-Googol(Googol) is the Bi-Super Googol, and then the Tri-Super Googol, and then with tetra, penta, hexa, hepta, octa, nona (or ennea), deca, and so on.

But what is a Googol-Super Googol?

That is called a Mega Googol.

And then a (Mega Googol)-Super Googol is a Bi-Mega Googol, and then Tri-Mega Googol, and then with tetra, penta, hexa, hepta, octa, nona (or ennea), deca, and so on.

And then we can continue with -giga, and then -tera, and then -extra, and so on. This is a list of prefixes that i made (yes, there are actually some SI prefixes in there).

-GiGa

-Tera

-Extra

-Ultra

-Hyper

-Uber

-Alpha

-Gamma

-Beta

-Delta

-Eta

-Zeta

-Omega

-Omni

Pretty long, eh?

But we won't continue adding prefixes forever.

Instead, we will call it * nth googol *

Ok?

So, what is a googolth googol?

That is a 2nd class googol.

And a (Super Googol)th googol?

That is a 2nd class Super Googol.

And then we can continue with -mega, and then -giga, -tera, -extra, and so on.

But what is a 2nd class googolth googol?

That is a 3rd class googol.

And then, we got a 4th class googol, and then 5, 6, 7, 8, 9, 10, and so on.

But...

What is the googolth class googolth googol?

That, my friend, is the almighty...

**ULTIMATE GOOGOL!!!!!!!!!!!!!!!!!!!!!!!**

Whoa. That is a REALLY BIG number.

## Expansions

We can actually continue expanding the Ultimate Googol by changing the googols by Ultimate Googols and then get the Bi-Ultimate Googol and then the Tri-Ultimate Googol and then with -tetra, -penta, -hexa, -hepta, -octa, -nona (or -ennea), -deca, -centa (100), and so on.

### Aarex Expansion

He defined:

A googolth class googolth googol is a (1,2)-class googol

A (1,2)-class googolth googol is a (2,2)-class googol

A (Googol,2)-class googolth googol is a (1,3)-class googol

A (Googol,Googol)-class googolth googol is a (1,1,2)-class googol

A (Googol,Googol,Googol,...,Googol,Googol,Googol)-class googolth googol (where there are a googol entries) is ULTIMATE GOOGOL V2
