Simple Set Game Proof Stuns Mathematicians

Simple Set Game Proof Stuns Mathematicians | Quanta Magazine

In a series of papers posted online in recent weeks, mathematicians have solved a problem about the pattern-matching card game Set that predates the game itself. The solution, whose simplicity has stunned mathematicians, is already leading to advances in other combinatorics problems. Invented in 1974, Set has a simple goal: to find special triples called "sets" within a deck of 81 cards.
