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.

## Etymology

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