You can use the digits 1,2,and 3 once only and any mathematical symbols you are aware of, but no symbol is to be used more than once. The challenge is to see if you can make the largest numbers.
Here are some numbers to set the ball rolling: 321, 21to the third power, (3/.1)to the second power.

bigger than nicks by Jonathan Waltz)
also this method wouldn't work, as the factorial can only operate on positive integers. Nicks prefactorial number is the same as 10^8, wheras yours is 10^68.3178..., which is certainly smaller (so far so good), but the result is not an integer, so that factorial cannot be computed.
