seventy two sectillion.
Unfortunately, there is no such number. Please check your spelling and re-submit.
now i MAY be wrong, but ill go ahead: Million Billion Trillion Quadrillion Pentillin Sectillion (Don't know the one for 7) Octillion And that's all I can figure, hope I was help XP Edit: It goes by the common scientific naming of multiplicity, just like what is described above, but you don't use the prefixes used for geometry like what is described. You instead use the common prefixes used in naming chemical compounds. Here's the list: Million Billion Trillion Quadrillion Quintillion Sextillion Septillion Octillion Nonillion Decillion Undecillion Duodecillion and so on and so forth...duodecillion is actually 10,000,000,000,000,000,000,000,000,000,000,000,000,000 so if you need to really count anything more than that you're probably at a molecular level and would simply call it 10 to the 39th power. :)
