Sydler multiplier 15-75

3D Model

Applying Sydler’s 1953 construction to the angles 15° and 75° works much less neatly than 30° and 60°, which comes out miraculously neatly.

This can be combined with the 30°/60° version to construct a 15° single angle polyhedron.

I subsequently found a simpler way to construct such a polyhedron.
