The pentacthuliterator (also called pentacthulhum ba'al) is equal to E100#^^^#>#100 = E100(...(((#^^^#)^^^#)^^^#)...)^^^#100 (100 ^^^#'s) in Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian.

Approximations in other notations Edit

Notation Approximation
BEAF \(\{X,X^2,1,2\}\ \&\ 100\) (weaker bound)

X^^^(X+1) & 100 (stronger bound)

Bird's array notation ???
Hyperfactorial array notation \(100![100(1)100]\)
Strong array notation ???
Fast-growing hierarchy \(f_{\Gamma_{99}}(100)\)
Hardy hierarchy \(H_{\Gamma_{99}}(100)\)
