Ghoggol is a number in the googol family, coined by adding an upgrading -g- infix, transforming googol into g(3, 50, 50) = g(4, 2, 50), fifty-pentated-to-the-second. It was formerly known as simply Goggol, without the silent H, until the name conflicted with the much larger number of Jonathan Bowers. The -h- infix came to be known as standing for "formerly high".[1] In arrow notation, this number is equal to \(50 \uparrow\uparrow 50\).
