Simon Nickerson's Research
Up until 2005, I was a
PhD student in
Mathematics
at the
University of Birmingham, supervised
by
Professor R. A. Wilson.
My research was in finite group theory, and I was particularly
interested in computations with finite simple groups and related groups,
such as their automorphism groups and covers.
In my PhD thesis, I constructed
characteristic zero representations for some quasisimple groups for
the ATLAS
of Finite Group Representations. I also found standard generators
for those groups which didn't have them defined.
Here is an
unflattering photo of me giving a talk.
 An Atlas of Characteristic Zero Representations  PhD thesis and representations (submitted as a CDROM)
 Semipresentations for the sporadic simple groups
 Preprint of article (article published in Exp. Math.)
 A 20 minute talk I gave at the
Nikolaus 2004 Conference at RWTHAachen.
 Rational reconstruction of representations
 Maximal subgroups of the sporadic almostsimple groups  my
MPhil thesis.

The Mathieu groups

Moggie 
a Java applet for playing with the MOG of Robert Curtis. You might
find it helpful if you're studying the sporadic Mathieu group
M_{24}
or the wonderful
S(5,8,24) Steiner system. Source code available on request.
 An essay I wrote under the supervision
of
Dr. J. Saxl
for Part III
of the Cambridge Mathematical Tripos. It presents a construction
of the Mathieu groups (especially
M_{24}) and the
Conway group
.0 = 2.Co_{1}.

This page was last updated on 30th January 2010, but I last did any serious research in 2005! I am now a software developer rather than a mathematician.
