Quatillion is the largest number ever, and it is so large it is infinitely larger than infinity, and almost a quatillion times larger (but not quite, cos that'd be impossibly huge.) The sum to find one Quatillion is as follows:
1 Googol X 1 Quatillion
To put the imenseness of quatillion into perspective, if you had one quatillion grains of sand, you would not be able to fit even one jillionth of them into the universe. Nobody has ever done anything that warranted the use of a number so high as "Quatillion" as it is really big. In your life time, you wont do anything a Quatillion times.
No example warrants the use of "Quatillion" as it is just too big.
