Triple Centifact is the third mixed factorial of 100 or mixed factorial of double centifact, written as 100*** or 100*3 in multiple mixed factorials. The term was coined by SpongeTechX. It is smaller than \(\{10,10,\{10,10, \{100,101,97\}\}\}\) in BEAF, and it is therefore smaller than a boogolduplex.


The name of this number is based on the word triple and the number centifact.
