Abstract We give a description of the double cover of Conway's group in terms of right multiplications by 3 × 3 matrices over the octonions. This leads to simple sets of generators for many of the maximal subgroups, including a uniform construction of the Suzuki chain of subgroups. 
THERE IS NO Sz(8) IN THE MONSTER
As a contribution to an eventual solution of the problem of the determination of the maximal subgroups of the Monster we show that there is no subgroup isomorphic to Sz(8). This also completes theExpand
U-Duality and the Leech Lattice
It has recently been shown that the full automorphism group of the Leech lattice, Conway's group Co_0, can be generated by 3 x 3 matrices over the octonions. We show such matrices are of type F_4 inExpand
On infinitely generated groups whose proper subgroups are solvable
Abstract In this work infinitely generated groups are considered whose proper subgroups are solvable and in whose homomorphic images finitely generated subgroups have residually nilpotent normalExpand

Octonions and the Leech lattice
Abstract We give a new, elementary, description of the Leech lattice in terms of octonions, thereby providing the first real explanation of the fact that the number of minimal vectors, 196560, can beExpand

Finite Quaternionic Reflection Groups
In this article the quaternionic reflection groups are classified. Such a group is defined so as to generalize the notion of reflection groups appearing in [4, 171, i.e., it is a group of linearExpand
