Abstract: Many vertex operator algebras, such as the Moonshine module for the Monster finite simple group, contain tensor powers of the central charge 1/2 Virasoro vertex operator algebra as subalgebras. Motivated by the problem of constructing integral forms in these vertex operator algebras, I will discuss how to obtain integral forms in tensor powers of the central charge 1/2 Virasoro vertex operator algebra and their modules. The role of binary linear codes in the construction suggests that these integral forms could have interesting automorphism groups.
