Abstract
Let B be a block with abelian defect group D of a quasisimple group G, such that G/Z(G) has exceptional Schur multiplier. We show that, B is isotypic to its Brauer correspondent in NG(D) in the sense of Broué. The proof uses methods from a previous paper [B. Sambale, Broué's isotypy conjecture for the sporadic groups and their covers and automorphism groups, Internat. J. Algebra Comput. 25 (2015) 951-976], and relies ultimately on computer calculations. Moreover, we verify the Alperin-McKay conjecture for all blocks of G.
