Informally, **zillion** means a very large, indefinite quantity. It is often used for humor and exaggeration, with variants such as **gazillion** or **bazillion**.

Andrew Schilling (the four-year-old creator of zootzootplex) invented **sillion** ("like zillion, but sillier") and **sillyillion** ("like sillion, but bigger").^{[1]} San Francisco eccentric and protester Frank Chu often writes zillion-like numbers on his signs, such as **deskrothullion**, **cletrostallion**, or **resgroshillion**.^{[2]}

## *n*-zillion Edit

Conway and Guy defined ** n-zillion** to mean \(10^{3n+3}\).

^{[3]}In cooperation with Allan Wechsler, the system was extended to

*x*illi

*y*illi

*z*ilion \(= (10^6x+10^3y+z)\)-zillion, using "n" for

*x*,

*y*, or

*z*lest any of them be zero. For example, a quadrillitrillinillion is \(10^{3\left(10^6\cdot 4+10^3\cdot 3+0\right)+3} = 10^{3\cdot 4003000 + 3}\) in the American system. In the system formerly used in the UK,

*n*-zillion would instead be \(10^{6n}\).
