This shape is based upon the sacred geometry of the icosidodecahedron, a 32 faced Archimedean solid. An icosidodecahedron can be created by the intersection of six regular decagons. If you inscribe a 10 pointed regular decagram star
https://en.m.wikipedia.org/wiki/Decagram_(geometry) within each of the six decagons, and then remove the outer decagons, you get his beautiful 30 pointed icosidodecahedral star. A similar 30 pointed icosidodecahedral star can also be created by the intersection of twelve 5 pointed stars, which can be seen here:
