In the naming system currently used, 10^99 is duotrigintillion, so a googol is ten duotrigintillion.

Numbers up to 10^3003 have names in our system. That number is a millinillion. You will find the names of all unique names of powers from 10 from 3 (thousand) to 3003 (millinillion) here: http://home.kpn.nl/vanadovv/BignumbyN.html

Another example:

10^1725 = quattuorseptuagintaquingentillion

Googolplex doesn't have a name in our system. In the "Conway-Wechsler System", this is the name for googolplex:

Anyway, googolplex has nothing on these numbers:

Skewes' number
Moser's number
Graham's number (largest number ever used in a serious math proof)

Go halfway down http://www-users.cs.york.ac.uk/~susan/cyc/b/big.htm

to understand this number, called as 'mega'



Go ahead, try to understand it, it will blow your mind, if you can even begin to fathom it. Truly fascinating.

Also try to understand Moser's and Graham's numbers. Quite hard to fathom. Googolplex is infinitesimally small compared to them!


BTW, this site is great... enter any large number into it (upto 10^303 = centillion), and it will name it, using the standard system! For example:
