Dear IntersectSet( GapUsers, FiniteGeometers );

I wrote some programs for handling finite Galois geometries. In the first
step I generated difference sets for PG(2,q) (q<500), difference families
for PG(3,p) (p<85), and studied the orbits of Singer group in PG(2,q). Next,
I plan to improve them for a program, which offers an environment for
studying problems in finite geometries. If

- you are interested in such a program, or
- you have some ideas, how to do it, and what to do, or
- you made or plan to make something similar, or
- you have a problem, which needs this approach,

then please, write me, either through this forum, or directly to my address:


If you are interested in my outputs and programs (versions under
preparation), then you can read them on the machine


using anonymous ftp. The path to the files is


In this directory you can find a report (report.tex) written in LaTeX,
the difference sets (182KB), difference families (795KB), and some programs
and output files with the types of orbits. The programs use the package

Best regards,

Ferenc Wettl (wettl@euromath.vma.bme.hu)
