Greegolda-dusuthrexigong is equal to E100000##100000#100000#100000#3, or E100000##100000#100000#(100000##100000#100000#(100000##100000#100000#100000)), using Extended Hyper-E Notation.[1] The term was coined by Sbiis Saibian.

Etymology

The name of this number is based on the number "greegold", short for 'greedy golden googol', and the suffix '-suthrexigong', implying 100,000 instead of 100 and referring to the #3 on the end.
