RDS is a package for finding relative difference sets in non-abelian groups. Especially those defining projective planes.
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.Marc Roeder (roeder.marc[at]gmail.com) Last Update: 16th November 2013
