Quadrunculus

Quadrunculus is equal to \( \{ X,100,4 \}\ \&\ 10 \) using the array of operator and BEAF. Its array is intended to have a 100-dimensional hexational hypercube, which has geegol entries. The term was coined by Jonathan Bowers. It is intended to be comparable to Sbiis Saibian's hexacthulhum.
Since BEAF has not been formalised by Bowers at this level, this number is currently ill-defined.
==Approximations==
Since it is not defined by now, the following approximation is just an expected value under climbing method (strong bound):
Notation 	Approximation
Bird's array notation 	\(\{10,100[1[1 \backslash 2¬2]1[1 \backslash 2¬2]2]2\}\)
Extended Cascading-E notation	E10#^^^^#100
Fast-growing hierarchy 	\(f_{\varphi(2,0,0)}(100)\)
Hardy hierarchy 	\(H_{\varphi(2,0,0)}(100)\)
Slow-growing hierarchy (using this system
of fundamental sequences)	\(g_{\psi_0(\Omega_2^{\Omega_2 2})}(100)\)
