Background:
In 1991, while interested in large numbers like a centillion and a "googolgong", I invented a large number notation to reach a finite number so large that it was in fact infinite. This became my Polygon Notation. 20 years later, in 2011, I revisited it, creating Hyper-E Notation, a simpler way to describe my polygon notation from 1991. In the years from 2011-2015, this notation was expanded upon becoming The Extensible-E System, often abbreviated to ExE.
Extensible-E is an "extensible" framework that allows one to create more and more powerful notations using 5 basic "Laws". Extensible-E is broken down into several notations of increasing strength, each one building on the last.
Below you will find the various currently defined levels of ExE. Click on the links to see their definitions.
