Consider a finite dimensional vector space V over a finite field F q. We give a minimal generating set for the ring of invariants F q [V⊕ V⁎] GL (V), and show that this ring is a Gorenstein ring but is not a complete intersection. These results confirm a conjecture of Bonnafé and Kemper [3, Conjecture 3.1].
