Quadragintuple Stacker King

Quadragintuple Stacker King or icosapentahectakulus is equal to \(\underbrace{520\ \&\ 520\ \&\ 520 \cdots 520\ \&\ 520\ \&\ 520}_{\text{520 520's}} = \{520,520/2\}\) using BEAF. This term was coined by XRQ CORPORATION.XRQ CORPORATION's Golapulus Series Accessed 2022-10-06. The array of operator is unformalized at this level.
==Approximations==
Since it is not defined by now, the following approximations are just expected values:
Notation 	Approximation
Bird's array notation	\(\{520,520 [1 [1 /_{518} 1,2 /_{519} 2]_1 2] 2\}\)
Fast-growing hierarchy (using this system
of fundamental sequences)	\(f_{\psi_0(\Omega_\omega)}(520)\)
