Sydler multiplier 15-75

Description

Applying Sydler’s 1953 construction to the angles 15° and 75° works much less neatly than [30° and 60°](https://sketchfab.com/3d-models/sydler-multiplier-30-60-version-3-028ffb19ab554505a44d4bf69e599908), which comes out miraculously neatly. This can be combined with the 30°/60° version to construct [a 15° single angle polyhedron](https://sketchfab.com/3d-models/single-angle-15-44c9b2d4303d4dea85bec7ed7a54051e). I subsequently found [a simpler way to construct such a polyhedron](https://sketchfab.com/3d-models/single-angle-15-coloured-8230e145f97c4daba4cfbaf317f0a55b).
