We study Siegel modular forms associated with the theta lift of twisted elliptic genera of K3 orbifolded with g' corresponding to the conjugacy classes of the Mathieu group M-24. For this purpose we rederive the explicit expressions for all the twisted elliptic genera for all the classes which belong to M-23 subset of M-24. We show that the Siegel modular forms satisfy the required properties for them to be generating functions of 1/4 BPS dyons of type II string theories compactified on K3 x T…
