Umbral moonshine
In mathematics, umbral moonshine is the name for a mysterious connection between the Mathieu group M24 and K3 surfaces, observed by Tohru Eguchi, Hirosi Ooguri, and Yuji Tachikawa (2011).
Cheng, Duncan & Harvey (2012) also observed that some of the functions appearing in umbral moonshine are Ramanujan's Mock theta functions and it is conjectured that there are infinite-dimensional graded modules, for prescribed finite groups, whose McKay-Thompson series are certain distinguished mock modular forms. This conjecture has been proved in Duncan, Griffin & Ono (2015).
