Nice to read about mathematics that involves Set! I found out about Set here on Hacker News several years ago, when I read Peter Norvig's blog post on the odds of not finding a set in the 12 cards [1]. I had never heard about the game before, but tried it and really liked it.

The simplicity of the rules, the mathematical nature of it, and the fact that adults and kinds can play together makes it such a great game. I continued with the analysis of finding the odds of not set in each round of play, and had fun doing so. It seems very difficult to find an analytical solution (and quite beyond me), but simulation was a nice project that gave some good insights into how the odds vary over the rounds played [2].
