A treseptuagintaquingentillion is equal to \(10^{1722}\) in the short scale and \(10^{3438}\) in the long scale by the Conway and Guy's naming system[1][2][3][4][5] as it is the 573rd -illion number.
In the long scale, \(10^{1722}\) is called septemoctogintaducentillion.[6]
Doug's Zillion[]
\(10^{1,722}\) is also called Doug's Zillion. This number originates from an episode of the Nickelodeon animated cartoon Doug, titled "Doug's Mail Order Mania". In this episode, the title character enters a fraudulent sweepstakes which purports to offer this amount in US$ as a prize. Said number is repeatedly referred to as a "zillion" dollars. It is 1,723 digits long.
Notably, the number is written out in full in the episode, taking up several pages of paper. Although it's impossible to see the whole thing at once, the size of the number can be determined by counting the number of zeros on one visible page, multiplying it by the total number of zero-filled pages, and adding the 21 zeros on the first page.
This is quite possibly the largest number ever explicitly referenced in a cartoon.
