Blocks with defect group [math]C_8 \times C_2[/math]
[math]{\rm Aut}(C_8 \times C_2)[/math] is a [math]2[/math]-group and [math]C_8 \times C_2[/math] is abelian, so there is only one possible fusion system. Hence every block with this defect group is nilpotent.
There is a unique [math]\mathcal{O}[/math]-Morita equivalence class.
