Ungol in zeroes

The ungol is equal to \(r(10^{50},1)\) in Rampant Array Notation or gogol squared a gogol times[1]. The number was coined by Googology Wiki user Nirvana Supermind. It is larger than Skewe's Number but smaller than Googolduplex.


The name is derived from googol and the prefix un- meaning 1.
