Wiman's sextic
In mathematics, Wiman's sextic is a degree 6 plane curve with four nodes studied by .
It is given by the equation (in homogeneous coordinates)
Its normalization is a genus 6 curve with automorphism group isomorphic to the symmetric group "S".

Awards.
He was elected a member of the Royal Swedish Academy of Sciences in 1905.
Work.
He introduced Wiman's sextic curve.
The main focus of his research was algebraic geometry and applications of group theory to geometry and function theory. He proved that for "n"  7, in less than "n"–2 dimensions, there are no groups of collineations that are isomorphic to the symmetric or alternating group on "n" symbols. He also determined all finite groups of birational transformations of
