Golden triangles on an icosahedron form a perfect decagon — new arXiv paper (v2)

A new paper on arXiv formalizes a 10-face wing set on the regular icosahedron where each face is a golden gnomon (36°–36°–108°), no two faces share an edge, and the midpoints of the free edges form a perfect regular decagon with closed-form radius R = (φ/2)ℓ. Motivated by a wind turbine blade design (GeoWind), but the result is purely geometric. [https://arxiv.org/abs/2603.00017](https://arxiv.org/abs/2603.00017)
