Grangol

Grangol (short for "grand googol") is equal to E100#100 = EEE...EEE100 (100 E's) =  (100 tens), using Hyper-E notation. The term was coined by Sbiis Saibian.

Grangol is close to Jonathan Bowers' giggol = E1#100, which seems slightly smaller. It is comparable only from a googologist's perspective, however &mdash; it can be shown that  < grangol, so the two numbers are arithmetically extremely far apart. This concept is related to the power-tower paradox.

Aarex Tiaokhiao called powergol refers same value of grangol.
