Dubolplex is equal to \(\{10,\{10,100 (1)(1) 2\} (1)(1) 2\}\) = {10,10, ... ,10 (with n tens)(1) 10,10, ... ,10 (with n tens)} where n is dubol. This term was coined by YouTuber Douglas Shamlin Jr.[1]

Notation Approximation
Bird's array notation \(\{10,\{10,100 [2] 1 [2] 2\}[2] 1 [2] 2\}\) (exact)
Cascading-E notation \(\textrm{E}10\#\text{^}\#*\#\text{^}\#100\#2\)
Hyperfactorial Array Notation \((100![1,[1,1,2],1,2])![1,[1,1,2],1,2]\)
Fast-growing hierarchy \(f_{\omega^{\omega2}}^2(100)\)
Hardy hierarchy \(H_{\omega^{\omega^{\omega2}}2}(100)\)
Slow-growing hierarchy (using Buchholz's hierarchy) \(g_{\psi_0(\Omega^{\Omega^{\Omega+\psi_0(\Omega^{\Omega^{\Omega+\omega}})}})}(100)\)
