-plex

The -plex suffix, when applied to argument \(n\), represents \(10^n\) according to Conway and Guy. This is based on the googolplex, which is \(10^{\text{googol}}\). \(10^{-n}\), conversely, is called n-minex (wordplay on plus:plex:minus:minex).

In the works of Jonathan Bowers, -plex has a more general and less formal definition: if a number n is \(f(10, 100)\) where \(f\) is some googological function, then n-plex is defined as \(f(10, n)\). For example, giggol = \(10\uparrow\uparrow 100\), and giggolplex is not \(10^{\text{giggol}}\) but \(10\uparrow\uparrow\text{giggol}\). Sbiis Saibian circumvents this problem by defining new prefixes such as -dex and -threx.
