W. T. Tutte conjectured that the coefficients \(t_{i, j}\) of his dichromate form unimodal sequences in \(i\) and \(j\) separately. P. D. Seymour and D. J. A. Welsh conjectured more generally that the same holds for the coefficients of the Tutte polynomial of an arbitrary matroid. We show, by an exa
