Using U.S. nomenclature. Limited values to numbers < 10^36. If allowing greater values, one googol (10^100) would come after 96.
0 could be inserted before '11', as 0's alternative name is 'nought'. - Dylan Nicholson (wizofaus(AT)hotmail.com), May 08 2006

			The three-letter numbers are one, two, six and ten.
