Original: Trigintillion , often cited as a word in discussions of names of large numbers , is not included in any of them , nor are any of the names that can easily be created by extending the naming pattern ( unvigintillion , duovigintillion , duoquinquagintillion , etc. ) .
Simplified: There is also the number Googol , which is a 1 with one hundred zeros behind it , and the number Googolplex , which is a 1 with a Googol of zeros behind it .
