Named by André Weil after the mathematicians Kodaira, Kummer and Kähler and the mountain K2, K3 surfaces are one of the prominent classes of complex surfaces. Their (finite) symmetries are closely related to the Mathieu group M_{24}. This group, discovered in the 19th century, is one of the finite sporadic simple groups.
