## Alternative names

This number is also called **tetrillion** in Russ Rowlett's Greek-based naming system.

Aarex Tiaokhiao gave the name **tetillion**, referring to the value of this number. He also calls 1012 **dudoocol**, **12-noogol**, or **goonaoldecault**, and it's equal to a(10,100,0)x[10] in Aarex's Array Notation.

Wikia user NumLynx gave the name **quadrasand** for this number's short scale value.

Nicolas Chuquet coined **byllion** for 1018 (not to be confused with 1016), according to the *Triparty en la science des nombres*, which was previously lost and not rediscovered until 1880. Later it became billion in long scale.

Username5243 gave the name **niloogolnoniplex**, referring to the short scale value of this number.

BlankEntity calls this number **Joogol**.
