The duprimibol is equal to s(3,2,3,3) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow3\rightarrow2\rightarrow3\).


The name of this number is based on the prefix "bi-" and the number "duprimitol".


Notation Approximation
BEAF \(\{3,3,2,3\}\)
Hyper-E notation \(E2\#\#2\#\#(E(3)1\#1\#3)\#(E(3)1\#1\#3)\)
Chained arrow notation \(3\rightarrow3\rightarrow3\rightarrow2\rightarrow3\) (exact)
Hyperfactorial array notation \((4!2)![2,2]\)
Fast-growing hierarchy \(f_{\omega2+1}(f_4(2))\)
Hardy hierarchy \(H_{\omega^{\omega2+1}+\omega^4}(2)\)
Slow-growing hierarchy \(g_{\varphi(2,0,\zeta_0)}(3)\)
