Like the roofs of the dodecahedron, the set of 12 trajectories of the icosahedron corresponding to its 12 vertices can be decomposed into 3 reciprocally orthogonal rectangles (however, having a particular--"golden"--ratio of their sides' lengths for the star to be regular).

The icosahedron can be geometrically inverted to form a dodecahedron. Russian scientists, adding the dodecahedron structure to Sanderson's discovery, found that the greatest earthquake lines were on the dodecahedron grid.
The most suitable polyhedron to be used in spherical structures is the dodecahedron, for which the angle between two adjacent polygons is 1150.
Based on aforementioned design method, other polyhedrons in geometry, such as octahedron, dodecahedron and icosahedron, can be adopted to project homogeneous and non-singular cloaks similarly.
Or Hippasus, having put a dodecahedron in a sphere, may have broadcast the irrational to his ultimate detriment, but neither has anyone to this day squared a circle.

At the end of Elements, Euclid addresses the five regular solids: the pyramid, the cube, the octahedron, the icosahedron, and the dodecahedron. It can be demonstrated that the side of the icosahedron and the side of the dodecahedron are incommensurable with each other and each with the sides of the pyramid, cube, and octahedron.
