Construction of Commutator Blueprints

Commutator blueprints can be seen as blueprints for constructing RGD-systems over ${\mathbb{F}}_2$ with prescribed commutation relations. In this paper we construct several families of Weyl-invariant commutator blueprints, mostly of universal type. Together with the main result of \cite{BiRGD} we obtain new examples of exotic RGD-systems of universal type over ${\mathbb{F}}_2$.
