On the symmetry of odd Leech lattice CFT

open access: yesJournal of High Energy Physics
We show that the Mathieu groups M 24 and M 23 in the isometry group of the odd Leech lattice do not lift to subgroups of the automorphism group of its lattice vertex operator (super)algebra.

A symplectic fission scheme for the association scheme of rectangular matrices and its automorphisms

open access: yesAIMS Mathematics
In this paper, a symplectic fission scheme for the association scheme of $ m\times n $ rectangular matrices over the finite field $ \mathbb{F}_q $, denoted by $ {\rm{SMat}}(m\times n, q) $, is constructed, where $ q $ is a power of a prime number.
