The truprimibolplex is equal to s(3,3,3,4) in strong array notation.[1] It can be represented in chained arrow notation as \(3\rightarrow3\rightarrow3\rightarrow3\rightarrow3\rightarrow3\).

This number is also equal to s(3,3,1,5), s(3,1,1,6), or s(3,4,1,1,2).


The name of this number is based on the suffix "-plex" and the number "truprimibol".
