Let \(G\) be a finite group, \(k\) a field of characteristic \(p>0\) and \(T\) the direct sum of irreducible \(kG\)-modules. The authors describe a program for computing the algebra \(\text{Ext}^\ast_{kG}(T,T)\) and write down a multiplication table for that algebra. Some comments and remarks on the scope and difficulties of the project conclude the paper.
