Extensible-E System

The Extensible-E System (ExE) is a work-in-progress array notation by Sbiis Saibian. It is a blanket term for Hyper-E Notation, Extended Hyper-E Notation, Cascading-E Notation, Extended Cascading-E Notation, and any future extensions to come.

ExE could also be called "SAN" (Saibian's array notation), similar to BAN (Bird's array notation) or HAN (Hyperfactorial array notation or Hollom's array notation).
