Googolthrong is equal to $$10^{100{,}000{,}000{,}000}$$ = 101011 or E100,000,000,000 in Hyper-E Notation.[1][2] It can also be written more succinctly as 10^10^11 or E11#2. The name appears to be extrapolated from "googolgong" with the tri- prefix, meaning 3. It is equal to 1 followed by 100 billion zeros. It is 1011+1 digits long.

Aarex Tiaokhiao gave the name googoltrine, referring to the value of this number.[3] It is based on the number googol and the suffix -trine.
