We construct an $S_{3}$ -symmetric probability distribution on ${(a,b,c)in mathbb{Z}_{{geqslant}0}^{3},:,a+b+c=n}$ such that its marginal achieves the maximum entropy among all probability distributions on ${0,1,ldots ,n}$ with mean $n/3$ . Existence of such a distribution verifies a conjecture of Kleinberg et al. [‘The growth rate of tri-colored sum-free sets’, Discrete Anal. (2018), Paper No. 12, arXiv:1607.00047v1], which is motivated by the study of sum-free sets.
