Abstract

New constructions of braces on finite nilpotent groups are given and hence this leads to new solutions of the Yang{Baxter equation. In particular, it follows that if a group G of odd order is nilpotent of class three, then it is a homomorphic image of the multiplicative group of a finite left brace (i.e. an involutive Yang{Baxter group) which also is a nilpotent group of class three. We give necessary and sufficient conditions for an arbitrary group H to be the multiplicative group of a left brace such that [H;H] ⊂ Soc(H) and H=[H;H] is a standard abelian brace, where Soc(H) denotes the socle of the brace H.
