Double Centifact

Double Centifact is the second mixed factorial of 100 or mixed factorial of centifact, written as 100** or 100*2 in multiple mixed factorials. The term was coined by SpongeTechX. It is smaller than {10,10, {100,101,97}} in BEAF, and it is therefore smaller than a boogolplex.
== Etymology ==
The name of this number is based on the word double and the number centifact.
