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.

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

It is also the first -illion to exceed 1010 in the short scale.

It is equal to 1 million squared in the short scale and 1 million cubed in the long scale.
