On the structure of finite rings
The structure of standard modules. II. The case A1(1), principal gradation.
The structure of standard modules, I: Universal algebras and the Rogers-Ramanujan identities.
Matrix generators for the Harada-Norton group.
Standard generators for .
Construction of the fourfold cover of the Mathieu group .
A symplectic representation of
We explicitly construct a particular real form of the Lie algebra in terms of symplectic matrices over the octonions, thus justifying the identifications and, at the group level, . Along the way, we provide a geometric description of the minimal representation of in terms of rank 3 objects called cubies.
