Abstract The Alon–Tarsi conjecture states that if n is even, then the sum of the signs of the Latin squares of order n is non-zero (Alon and Tarsi, 1992). The conjecture has been proven in the cases n= p+ 1 (Drisko, 1997), and n= p− 1 (Glynn, 2010), where p is an odd prime. This paper is intended to be a concise and largely self-contained account of these results, along with streamlined, and in some cases, original proofs that should be readily accessible to a mathematician with a background in combinatorics. We also discuss the relation between the Alon–Tarsi conjecture and Rota’s basis conjecture (Huang and Rota, 1994), and present some related problems, such as Zappa’s extension of the Alon–Tarsi conjecture (Zappa, 1997), and Drisko’s proof of the extended conjecture for n= p (Drisko, 1998).
