Rontillion

Rontillion (formerly xonillion) is equal to \(10^{3 \times 10^{27}+3}\), or \(10^{3\text{ octillion }3}\), using the short scale definition of octillion.Illion Numbers by Jonathan Bowers (accessed Feb 7, 2023) It is the octillionth illion number. The term was coined by Jonathan Bowers. It is 3,000,000,000,000,000,000,000,000,004 digits long.

Rontillion is also known as one milliamilliamilliamilliamilliamilliamilliamilliamilliatillion according to Landon Curt Noll's The English name of a number.
