Blocks with defect group [math]C_8:C_4[/math]
[math]C_8:C_4[/math] is a metacyclic group of nonmaximal class, and so by [CG12] or [Sa12b] 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.
