Abstract

In this article, we study orbifold constructions associated with the Leech lattice vertex operator algebra. As an application, we prove that the structure of a strongly regular holomorphic vertex operator algebra of central charge 2424 is uniquely determined by its weight one Lie algebra if the Lie algebra has the type A3,43A1,2A_{3,4}^3A_{1,2}, A4,52A_{4,5}^2, D4,12A2,6D_{4,12}A_{2,6}, A6,7A_{6,7}, A7,4A1,13A_{7,4}A_{1,1}^3, D5,8A1,2D_{5,8}A_{1,2} or D6,5A1,12D_{6,5}A_{1,1}^2 by using the reverse orbifold construction. Our result also provides alternative constructions of these vertex operator algebras (except for the case A6,7A_{6,7}) from the Leech lattice vertex operator algebra.
