Sesquadragintillion

A sesquadragintillion or sexquadragintillion is equal to \(10^{141}\) in the short scale, or \(10^{276}\) in the long scale by Conway-Wechsler system.Conway and Guy. (1995) "The book of Numbers" CopernicusThe Conway-Wechsler SystemSteve Olsen, Big-Ass NumbersExtensions to the -illions I: Henkle, Conway, and RowlettFish. Conway's zillion numbers, July 25, 2021 Sesquadragintallion is an original name by Conway and sexquadragintallion is a simplified name.
In the long scale which is commonly used in France and Germany, \(10^{141}\) is called tresvigintilliard.
