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


The name of this number is based on the prefix "du-" and the number "primitol".

BEAF \(\{3,3,1,3\}\)
Hyper-E notation \(E2\#\#2\#\#(E(3)1\#1\#3)\)
Chained arrow notation \(3\rightarrow3\rightarrow3\rightarrow2\rightarrow2\) (exact)
Hyperfactorial array notation \(26![4!2]\)
Fast-growing hierarchy \(f_{\omega2}(f_4(2))\)
Hardy hierarchy \(H_{\omega^{\omega2}+\omega^4}(2)\)
Slow-growing hierarchy \(g_{\varphi(1,\zeta_0,0)}(3)\)
