Quinquagintillion

A quinquagintillion is equal to 10153 in the short scale, or \(10^{300}\) in the long scale by Conway and Guy's naming system.Big-Ass NumbersConway and Guy. (1995) "The book of Numbers" CopernicusThe Conway-Wechsler System
Jonathan Bowers coined quinquagintillion for this number.
In the long scale which is commonly used in France and Germany, 10153 is called quinvigintilliard.
