Statement

Erdős, Herzog and Piranian (1958) asked whether the regular n-gon maximizes the product of pairwise distances among n points of fixed diameter. After the recent discovery that it does not for even n, this paper proves the first exponential improvement over the n-gon's value, via a vector-field technique.

    The acknowledgments thank "Stijn Cambie, ChatGPT, and Quanyu Tang for discussion (in alphabetical order)" - a discussion credit, listed alongside the human colleagues, with no specific step attributed.

    An improved lower bound on the maximal product; the sharp maximizer for the 1958 question remains unknown.
