Fzgoogol

Fzgoogol is equal to googolgoogol = (10100)10100 = 10100*10100 = 1010102. The name is formed by applying the fz- prefix to a googol. Written as 1010102 it looks only slightly larger than a googolplex, though in reality you need to raise a googolplex to the 100th power to get a fzgoogol. It is 1 followed by exactly 100 times as many zeros as a googolplex has. It is equal to 1 followed by trestrigintillion (short scale) or septendecillion (long scale) zeroes. This number is slightly larger than a googolplex. It is 10102+1 digits long.
Writing down the full decimal expansion would take 1096 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
A fzgoogol is also an upper-bound to the googolbang.
SuperJedi224 calls this number Triangol (short for "triangle googol"), and it's equal to 10100 in a triangle in Steinhaus-Moser Notation.Big Box - Almost Infinite
RedBandServerYT calls this number googesimal-googolplex.
