This process can be continued indefinitely, but one has to stop somewhere. The name centillion (n = 100) has appeared in many dictionaries. A centillion is 10[size=x-small]303[/size] (1 followed by 303 zeroes) in the American system and a whopping 10[size=x-small]600[/size] (1 followed by 600 zeroes) in the European system.
Finally, there is the , the number 10[size=x-small]100[/size] (1 followed by 100 zeroes). Invented more for fun than for use, the googol lies outside the regular naming systems. The googol equals 10 duotrigintillion in the American system, 10 sexdecilliard in the European system, and 10 triacontatrillion in the proposed Greek-based system.
