One of the recent topics of interest in mathematical string theory is the study of the
Mathieu moonshine and how it is realised in a string theoretic framework. It was
shown by Eguchi, Ooguri and Tachikawa that the elliptic genus of the K3 surface has
connections to the dimensions of the irreducible representations of the M_24 Mathieu
group. In this talk, I shall give an overview of the (Mathieu) moonshine and present the
results of a study of the (twined) elliptic genera expansion of CY 5‐folds and relations to
sporadic groups.
