**The Card Game 'Set' and its structure**

Friday, March 6, 2015, 3:30pm

Ungar Building Room 402

**Abstract: **

'Set' is a card game based on pattern recognition. Interestingly, its rules can be encoded in the linear algebra of a four-dimensional affine space over the finite field with three elements. We will prove a geometric fact about this finite space- the largest a subset can be that avoids all lines is twenty- and use this to conclude a non-trivial fact about the game.
