Abstract: The analogue of the McKay-Thompson series for the proposed Mathieu groupaction on the elliptic genus of K3 is analysed. The corresponding NS-sectortwining characters have good modular properties and satisfy remarkablereplication identities. These observations provide strong support for theconjecture that the elliptic genus of K3 carries indeed an action of theMathieu group M24.
