What is a math trade?

Check out this page on BGG for additional information. The following paragraph is from their website:

“This is a trade between a whole bunch of people at once, using an algorithm to decide who should send their game to whom. Because of the algorithm used, you can only get a game you prefer over what you started with. (Or at worst, you may just keep your original game.)

Sometimes this kind of trade is called a “mathematical no-risk trade list.” This is just a longer name for the same thing.”
