Abstract: In this paper, we introduce the notion of entropic Niebrzydowski tribrackets or just entropic tribrackets, analogous to entropic (also known as abelian or medial) quandles and biquandles. We show that if [Formula: see text] is a finite entropic tribracket then for any tribracket [Formula: see text], the homset [Formula: see text] (and in particular, for any oriented link [Formula: see text], the homset [Formula: see text]) also has the structure of an entropic tribracket. This operation yields a product on the category of entropic tribrackets; we compute the operation table for entropic tribrackets of small cardinality and prove a few results. We conjecture that this structure can be used to distinguish links which have the same counting invariant with respect to a chosen entropic coloring tribracket [Formula: see text].
