The Dade group of a fusion system. [PDF]

open access: yes, 2009
We define the notion of the Dade group of a fusion system and show that some of the gluing and detection results for Dade groups of finite p-groups due to Bouc and Thévenaz in [S. Bouc and J. Thévenaz. Gluing torsion endo-permutation modules. (Preprint.)]

Prime order derangements in primitive permutation groups [PDF]

open access: yes, 2011
Let G be a transitive permutation group on a finite set Ω of size at least 2. An element of G is a derangement if it has no fixed points on Ω. Let r be a prime divisor of |Ω|.

Computing in permutation groups without memory [PDF]

open access: yes, 2013
Funding: UK Engineering and Physical Sciences Research Council (EP/K033956/1)Memoryless computation is a new technique to compute any function of a set of registers by updating one register at a time while using no memory.

Minimal and random generation of permutation and matrix groups [PDF]

open access: yes, 2012
We prove explicit bounds on the numbers of elements needed to generate various types of finite permutation groups and finite completely reducible matrix groups, and present examples to show that they are sharp in all cases.

The group of endotrivial modules for the symmetric and alternating groups. [PDF]

open access: yes, 2010
We complete a classification of the groups of endotrivial modules for the modular group algebras of symmetric groups and alternating groups. We show that, for n ≥ p2, the torsion subgroup of the group of endotrivial modules for the symmetric groups is ...

On base sizes for symmetric groups [PDF]

open access: yes, 2011
A base of a permutation group G on a set is a subset B of such that the pointwise stabilizer of B in G is trivial. The base size of G, denoted by b(G), is the minimal cardinality of a base.

Topics in computational group theory : primitive permutation groups and matrix group normalisers [PDF]

open access: yes, 2012
Part I of this thesis presents methods for finding the primitive permutation groups of degree d, where 2500 ≤ d < 4096, using the O'Nan-Scott Theorem and Aschbacher's theorem. Tables of the groups G are given for each O'Nan-Scott class.

Endo-permutation modules as sources of simple modules. [PDF]

open access: yes, 2003
The source of a simple $kG$-module, for a finite $p$-solvable group $G$ and an algebraically closed field $k$ of prime characteristic $p$, is an endo-permutation module (see~\cite{Pu1} or~\cite{Th}). L.

Most primitive groups are full automorphism groups of edge-transitive hypergraphs [PDF]

open access: yes, 2014
We prove that, for a primitive permutation group G acting on a set X of size n, other than the alternating group, the probability that Aut (X,YG) = G for a random subset Y of X, tends to 1 as n → ∞.

Permutation inference for the general linear model [PDF]

open access: yes, 2014
Permutation methods can provide exact control of false positives and allow the use of non-standard statistics, making only weak assumptions about the data.
