Indecomposable integral representations

Complete list of indecomposable integral representations:

Name Dim $(1,2,3) \mapsto $
Triv $1$ $\left(\begin{array}{r}1\end{array}\right)$
$J$ $2$ $\left(\begin{array}{rr}0 & 1\\-1 & -1\end{array}\right)$
$R$ $3$ $\left(\begin{array}{rrr}0 & 1 & 0\\0 & 0 & 1\\1 & 0 & 0\end{array}\right)$
The decomposition of an arbitrary integral representation as a direct sum of indecomposables is unique.
