Blocks with defect group [math]M_{16} \cong \langle x,y|x^8=y^2=1, yx=x^5y \rangle[/math]

[math]M_{16}[/math] is a metacyclic group of nonmaximal class, and so by [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.
