DETAILS

Savnik used Donald Bell's method to make a wooden model of a Bilinski dodecahedron. In 1959, Savnik was Bilinski's student at the University of Zagreb (Croatia) [4]. From a mathematical viewpoint, the main problem is calculating the angle between the working table and the basic face of the wooden stick so that the cut produces a golden rhombus.
