Martin Gardner’s minimum no-3-in-a-line problem

Title

Abstract

In the October 1976 Mathematical Games column of Scientific American, Martin Gardner posed the following problem: “What is the smallest number of [queens] you can put on an [n-by-n chessboard] such that no [queen] can be added without creating three in a row, a column, or a diagonal?” We’ll give a history and show how to turn this combinatorial problem into an algebraic one – one about the zeros of a polynomial – that results in a lower bound. Many opportunities for further research will be shared.
