Notation 	Approximation
BEAF 	\(\{100,101(X \uparrow\uparrow\uparrow\uparrow\uparrow X) 3\}\)Using particular notation \(\{a,b (X \uparrow\uparrow X) 2\}\) for \(X \uparrow\uparrow b\ \&\ a\) (weak bound, non-climbing)
\(\{100,101(X \uparrow\uparrow X^{4}) 3\}\) (strong bound, climbing)
Bird's array notation 	\(\{100,101[1 \backslash 1 \backslash 1 \backslash 1 \backslash 2]3\}\)
Fast-growing hierarchy	\(f_{\varphi(4,0)\times 2}(100)\)
Hardy hierarchy 	\(H_{\omega^{\varphi(4,0)\times 2}}(100)\) \(= H_{\varphi(4,0)^2}(100)\)
Slow-growing hierarchy	\(g_{\vartheta(\varphi(4,{\Omega 2}) 2)}(99)\)
