Nucleaxul is equal to 200![[200200]], using Hyperfactorial array notation.[1] The term was coined by Lawrence Hollom.


The name of this number comes from the word "nuclear" and the number "Faxul".


Notation Approximation
Fast-growing hierarchy \(f_{\varepsilon_0}(199)\)
Hardy hierarchy \(H_{\varepsilon_0}(200)\)
Slow-growing hierarchy \(g_{\theta(\varepsilon_{\Omega+1}+\omega,0)}(199)\)
Extended Cascading-E notation \(\textrm E200\#\text{^^}\#200\)
BEAF \(200\uparrow\uparrow198\&200\)
Bird's array notation \(\{200,100[1\backslash2]2\}\)
