Barth Decic
The Barth decic is a Decic Surface in complex three-dimensional projective space having the maximum possible number ofOrdinary Double Points (345). It is given by the implicit equation

is the Golden Mean and 
is a parameter (Endraß, Nordstrand), taken as 
in the above plot.The Barth decic is invariant under the Icosahedral Group.See also Algebraic Surface, Barth Sextic, Decic Surface, Ordinary Double Point
