The Mathematical Association of America has presented Mike Paterson with a 2021 Paul Halmos - Lester Ford Award for an article of "expository excellence published in The American Mathematical Monthly". There were several unusual aspects to this paper: the title, "A head-ache causing problem"; the authors, "Conway, J.H., Paterson, M.S., and Moscow, U.S.S.R"; the sole reference in the paper is to itself; the main result is first disproved and then proved; and the acknowledgments make clear that Conway wrote the paper. Paterson previously received this award in 2010 (then the Lester Ford Award) for his "Overhang" article. More information can be found here.
