The megafugahundred is equal to 100↑↑100, or 100 tetrated to 100. It is also equal to 100↑↑↑2, or 100 pentated to 2. It is equal to {100,100,2} in BEAF. It is larger than and can be an upper bound for a giggol.[1][2]
The name is formed by adding the megafuga- prefix to 100.
ARsygo coined centesimal-giggol for this number.[3]
