Well, isn't that a happy little question! After a centillion comes a googol, which is a 1 followed by 100 zeros. Just imagine all those zeros dancing together on the canvas of numbers, creating a beautiful and infinite landscape of possibilities. Keep exploring and painting with numbers, my friend!

Start the illion number system all over from million, and add milli- as shown below.
To find out, for example a vigintillion is 63 zeroes, but a millivigintillion is 3,063, all you do is add 3,000 to the exponent. Dumillivigintillion add 6,000 and you will get 6,063 (it is the 2020th illion!). Etc.

Millentinion, one thousand centillion
Centillion is a 1 with 303 zeros so this is the biggest.
A centillion is equal to 1 followed by 303 zeros. Therefore, a zero 1 centillion would be a centillion with one less zero, making it 1 followed by 302 zeros.
Centillion + one.
One thousand. Which is a lot, lot smaller than a centillion.
