Multiversoogol

is equal to \(\{100,100[1[2\backslash1,2\neg2]2]2\}\) in Bird's array notation, using the modified Hierarchical Hyper-Nested Array Notation. The term was coined by googology user .
It is intended to be comparable to TREE(3), although there is no formal proof on the growth rate of TREE(n).
