Abstract

In this article, we construct explicitly certain moonshine type vertex operator algebras generated by a set of Ising vectors II such that (1) for any efIe\neq f\in I, the subVOA VOA(e,f)\mathrm{VOA}(e,f) generated by ee and ff is isomorphic to either U2BU_{2B} or U3CU_{3C}; and (2)the subgroup generated by the corresponding Miyamoto involutions {τeeI}\{\tau_e|\,e\in I\} is isomorphic to the Weyl group of a root system of type AnA_n, DnD_n, E6E_6, E7E_7 or E8E_8. The structures of the corresponding vertex operator algebras and their Griess algebras are also studied. In particular, the central charge of these vertex operator algebras are determined.
