Unoctogintillion

An unoctogintillion is equal to 10246 in the short scale, or 10486 in the long scale by Conway and Guy's naming system.Conway and Guy. (1995) "The book of Numbers" Copernicus
In the long scale which is commonly used in France and Germany, 10246 is called unquadragintillion.
SuperJedi224 calls this number (in short scale) ter-tritillion-Illions - Almost Infinite.
