Noventrigintillion

A noventrigintillion or novemtrigintillion is equal to \(10^{120}\) in the short scale, or \(10^{234}\) in the long scale by Conway and Guy's naming system.by Conway-Wechsler system.Conway and Guy. (1995) "The book of Numbers" CopernicusSteve Olsen, Big-Ass NumbersThe Conway-Wechsler SystemExtensions to the -illions I: Henkle, Conway, and RowlettFish. Conway's zillion numbers, July 25, 2021 Noventrigintallion is an original name by Conway and novemtrigintallion is a modified name.
In the long scale which is commonly used in France and Germany, \(10^{120}\) is called vigintillion.

The Shannon number, named after , is also equal to \(10^{120}\), and is an estimate of the game complexity of chess.B. Blasius and R.

Programming a Computer for Playing Chess Philosophical Magazine. 41 (314) It is approximately equal to the number of possible 40 move (80 ply) games, 40 moves being a conservative estimate of the length of a chess game. It is neither the number of possible positions (estimated to be between \(10^{43}\) and \(10^{45}\)) nor the number of possible games.
