Seeding a tournament bracket, where you try to balance the top seeds in the various parts of the draw, follows a similar principle. In the familiar 16-team regions of the NCAA tournament, you have a Rule of 17 (1 vs. 16, 8 vs. 9, 4 vs. 13, 5 vs. 12...).

From there it's not particularly complicated to go up to 32 teams, and if you drop to 8 or 4, most of us have those pairings memorized. But if you wanted to, say, seed EVERY institution in the NCAA, down to Division III, there are 1,000-some schools and you'd need a 10-round tournament (plus some play-in games). And I really hope none of you have those pairings memorized. But you could use the Rule of 2,049 (2^11 + 1) to determine that the 961 seed would play the 1087 seed, then use the Rule of 1,025 (2^10 + 1) to match that game up with the 64 seed.

I've never thought more about how I remove eggs from the carton as I have since Monday. Does anyone else find themselves rearranging the eggs in the carton after a family member removes them "incorrectly"? Or is that just me?
