Some cohomology rings
This is Version 3. It is now obsolete, having been superseded
by Simon
King's computations page in Summer 2008.
This version was meant to supersede Version 2, which was moved from Wuppertal to Jena in Autumn 2008.
Note however that many groups in Version 2 are not covered by Version 3,
and that Version 2 is currently the last version to include information
on the essential ideal.
