We determine the numerical invariants of blocks with defect group Q2n × C2m and SD2n × C2m , where Q2n denotes a quaternion group of order 2, C2m denotes a cyclic group of order 2, and SD2n denotes a semidihedral group of order 2. This generalizes Olsson’s results for m = 0. As a consequence, we prove Brauer’s k(B)-Conjecture, Olsson’s Conjecture, Brauer’s Height-Zero Conjecture, the Alperin-McKay Conjecture, Alperin’s Weight Conjecture and Robinson’s Ordinary Weight Conjecture for these blocks. Moreover, we show that the gluing problem has a unique solution in this case. This paper follows (and uses) (Sambale, 2012, [21, 18]).
