In 1975 Stein conjectured that in every n × n array filled with the numbers 1,...,n with every number occuring exactly n times, there is a partial transversal of size n − 1. In this note we show that this conjecture is false by constructing such arrays without partial transverals of size n−(1/42)ln(n)
