What is a centrillion? Never heard of it.
No this is not a number. This word does not exist
Googelflex compose of 1000 zeroes times 10....
in my agenda at school, there is a little fact that the number centrillion, has 500 zeros. but, there is probaby a higher number out there. a googol is 1 followed by 100 zeros, but higher named number is a googolplex which is one followed by googol number of zeros - that's a lot of zeros!
