Enalineicosans is equal to [1,20,1] ~ E80#19#2 using PlantStar's Debut Notation.[​1]​​ The term was coined by PlantStar. The number is currently ill-defined.


Note: due to the ill-definedness of the notation, the following approximation is just the intended values.

Notation Approximation
Arrow notation \(48\uparrow\uparrow(48↑↑20)\)
Chained arrow notation \(48\rightarrow(48\rightarrow 20\rightarrow 2)\rightarrow2\)
BEAF {48,{48,20,2},2}
Bird's array notation {48,{48,20,2},2}
Hyper-E notation E[48]1#20#2
Hyper-E notation (base 10 equivalent) E80#19#2
Strong array notation s(48,s(48,20,2),2)
Hyperfactorial array notation (21!1)!1
Fast-growing hierarchy \(f_{3}(f_{3}(21))\)
Hardy hierarchy \(H_{ω^{3}2}(21)\)
Slow-growing hierarchy \(g_{\varepsilon_0[21]}(48)\)
