The Great Mega is equal to Circle(4) or ④ or Pentagon(4) in Steinhaus-Moser notation, or M(4,3) using Hyper-Moser notation. The term was coined by Aarex Tiaokhiao.[1]

In up-arrow notation, Great Mega is between $$4 \uparrow\uparrow\uparrow 5$$ and $$4 \uparrow\uparrow\uparrow 6$$.

Using the general notation proposed by Susan Stepney, Great Mega can be bounded more precisely in Hyper-E notation:
