Geodesic polyhedra are constructed by subdividing faces of simpler polyhedra, and then projecting the new vertices onto the surface of a sphere. A geodesic polyhedron has straight edges and flat faces that approximate a sphere, but it can also be made as a spherical polyhedron (a tessellation on a sphere ) with true geodesic curved edges on the ...
A Goldberg polyhedron is a dual polyhedron of a geodesic polyhedron. ... multiplier of 7. A clockwise and counterclockwise whirl generator, ...
The geodesic and Goldberg polyhedra are parameterized by integers m and n, with > and . T is the triangulation number, which is equal to T = m 2 + m n + n 2 {\displaystyle T=m^{2}+mn+n^{2}} . Icosahedral
Geodesic grids may use the dual polyhedron of the geodesic polyhedron, which is the Goldberg polyhedron. Goldberg polyhedra are made up of hexagons and (if based on the icosahedron) 12 pentagons. Goldberg polyhedra are made up of hexagons and (if based on the icosahedron) 12 pentagons.
Geodesic domes are the geometric dual of (a section of) a Goldberg polyhedron: a full geodesic dome can be thought of as a geodesic polyhedron, dual to the Goldberg polyhedron. In 1962, Donald Caspar and Aaron Klug published an article on the geometry of viral capsids that applied and expanded upon concepts from Goldberg and Fuller. [ 10 ]

The pentakis icosidodecahedron is a common geometry for geodesic domes derived from the icosahedron. Buckminster Fuller referred to it as the 2-frequency alternate geodesic subdivision of the icosahedron, because the edges are divided into 2 equal parts and then lengthed slightly to keep the new vertices on a geodesic great circle, creating a polyhedron with two distinct edge lengths and face ...
