"The Cascading-E notation (E^ for short) is a further extension and generalization of Hyper-E notation introduced by Sbiis Saibian in January 22, 2013. The limit of its growth rate is comparable to \\(f_{\\varepsilon_0}(n)\\) in FGH, making it about as powerful as tetrational arrays in BEAF. E^ is part of the general Extensible-E System, which includes all future extensions of the notation, such as Extended Cascading-E Notation."@en .
