Not to be confused with tethrafact.

Tetrafact is the mixed factorial of 4, written as 4* or ((1+2)x3)4. It is equal to 6561. The term was coined by SpongeTechX. [1] It is also an output of the Exploding Tree Function: \(E(3) = 6561\)


The name of this number is based on Greek prefix "tetra-" and the word "factorial".
