What is the smallest number that can be written as the difference of 2 squares in 4 ways?

If you take Charlie's solutions, for example, and reverse the squares, the numbers will become increasingly negative and hence 'smaller' in that sense.
I'd like to add that this turned out to be an interesting problem, as is reflected by my rating.
