Query: Genus three curves and 56 nodal sextic surfaces   Catanese and Tonoli showed that the maximal cardinality for an even set of
nodes on a sextic surface is 56 and they constructed such nodal surfaces. In
this paper we give an alternative, rather simple, construction for these
surfaces starting from a non-hyperelliptic genus three curve. We illustrate our
method by giving explicitly the equation of such a sextic surface starting from
the Klein curve.
