Killillion

The killillion is equal to \(10^{3\left(10^{3,000}\right)+3}\) or \(10^{3 \textrm{novemnonagintnongentillion}+3}\).Illion Numbers by Jonathan Bowers The term was coined by Jonathan Bowers. In his naming system, it is the smallest positive integer with the letter "k" in the name.
Written out in scientific notation, a killillion is:
== Etymology ==
The name of this number is based on the suffix "-illion" and the SI prefix "kilo-".
