Googolbar

The googolbar is equal to \(100,000^{50,000} = 10^{250,000} = g(2,50000,100000)\) in the Ackermann's Generalized Exponential Notation, or googol to the 2,500th power. It is part of the googo- naming system. It is also called ten tresoctogintilliduotrigintatrecentillion in the short scale. It is 250,001 digits long.
Googolbar is also known as "ten treoctoginmilliatrecenduotrigintillion" according to Landon Curt Noll's The English name of a number.
Its full decimal representation is:
