The gungulus is equal to {10,100 (0,6) 2} in BEAF. Its structural array has 100600 entries total. The term was coined by Jonathan Bowers.[1]


Notation Approximation
Bird's array notation \(\{10,100 [1,7] 2\}\)

Hyperfactorial Array Notation \(100![1,[1,[1,5,2],1,2],1,3]\)
X-Sequence Hyper-Exponential Notation \(10\{X^{X^{X*6}}\}100\)
Fast-growing hierarchy \(f_{\omega^{\omega^{\omega 6}}}(100)\)
Hardy hierarchy \(H_{\omega^{\omega^{\omega^{\omega 6}}}}(100)\)
Slow-growing hierarchy \(g_{\vartheta(\Omega^{\Omega^{\Omega5+\omega}})}(100)\)
