Damit folgen die Elementarteiler $1$, $1$ und $8 + t - 4t^2 + t^3$. Für die Fittingideale gilt
$\text{Fit}_1(B) = (1)$, $\text{Fit}_2(B) = (1)$ und $\text{Fit}_3(B) = (8 + t - 4t^2 + t^{3})$.
Damit folgen die Elementarteiler $1$, $1$ und $2 - 5t + 4t^2 - t^3$. Für die Fittingideale gilt
$\text{Fit}_1(B) = (1)$, $\text{Fit}_2(B) = (1)$ und $\text{Fit}_3(B) = (2 - 5t + 4t^2 - t^{3})$.
