ALL GROUPS ARE OUTER AUTOMORPHISM GROUPS OF SIMPLE GROUPS

Journal of the London Mathematical Society, 2001
It is shown that each group is the outer automorphism group of a simple group. Surprisingly, the proof is mainly based on the theory of ordered or relational structures and their symmetry groups. By a recent result of Droste and Shelah, any group is the outer automorphism group Out (Aut T) of the automorphism group Aut T of a doubly homogeneous ...

Non-simple groups which are the product of simple groups

Archiv der Mathematik, 1989
This paper investigates the structure of groups with non-trivial center which can be written as a product of two simple subgroups. Examples must be covering groups of simple groups. For example \(2\cdot PSU(4,3)=AB\) where \(A\simeq PSp(4,3)\) and \(B\simeq PSL(4,3)\) and \(3\cdot PSU(4,3)=AB\) where \(A\simeq PSp(4,3)\) and \(B\simeq PSU(3,3).\) The ...

A Presentation for the Lyons Simple Group

1999
We give a presentation of the Lyons simple group together with information on a complete computational proof that the presentation is correct. This fills a longstanding gap in the literature on the sporadic simple groups. This presentation is a basis for various matrix and permutation representations of the group.

The group SK1 for simple algebras

K-Theory, 2006
An algebra \(A\) over a field \(F\) is a `central simple algebra' if, over the algebraic closure of \(F\), \(A\) is isomorphic to a matrix algebra. The square root of the dimension of \(A\) is called its `degree'. It is known that \(A\simeq M_n(D)\) for a central division algebra \(D\) over \(F\). We call the degree of \(D\) the `index' of \(A\). Let \(
