## About me

I worked at NUI, Galway,
Ireland from 2006 to 2008. After that, I left academia to work as a
software developer in the "real world"(TM).
All code is available under the terms of the GNU General Public
License (GPL).

## Random thoughts

A few observations about GAP as well as hints and pieces of code can be found
on
this
page.
## The RDS package

RDS
is a package for finding relative difference sets in non-abelian
groups. Especially those defining projective planes.

## GAP packages written for the
CHA
group

During my time in
Galway, I wrote the GAP
package
polymaking
which interfaces the geometry software
polymake. I also wrote the
package
HAPcryst
which is an extension to the GAP
package
HAP
and can be used
to calculate free resolutions of Bieberbach groups.
