【 摘 要 】

Let $C_p$ denote the cyclic group of order $p$, where $p geq 3$ isprime. We denote by $V_n$ the indecomposable $n$ dimensionalrepresentation of $C_p$ over a field $mathbb F$ of characteristic$p$. We compute a set of generators, in fact a SAGBI basis, forthe ring of invariants $mathbb F[V_2 oplus V_2 oplus V_3]^{C_p}$.
