Quadruple Centifact is the fourth mixed factorial of 100 or mixed factorial of triple centifact, written as 100**** or 100*4 in multiple mixed factorials. The term was coined by SpongeTechX. It is smaller than {10,10,{10,10,{10,10, {100,101,97}}}} in BEAF, and it is therefore smaller than a boogoltriplex.


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