We classify principal *2*-blocks of finite groups *G* with Sylow *2*-subgroups isomorphic to a wreathed *2*-group *C_{2^n}\wr C_2* with *n\geq 2* up to Morita equivalence and up to splendid Morita equivalence. As a consequence, we obtain that Puig's Finiteness Conjecture holds for such blocks. Furthermore, we obtain a classification of... Show more
