“A dodecahedron modified by the octahedron and cube from Nordmark, Sweden, is figured in Goldschmidt.”

“The cube, consisting of six square faces, is a common form either alone or in combination with other forms, especially the octahedron.”

“This six-point perspective, with the six vertices of an octahedron serving as the vanishing points, becomes the basis of his spherical paintings.”

“Copper, Cu, has been found associated with cuprite octahedra at Pedra Preta, where these minerals occur on talc and magnesite.”

“The octahedra range from 5 to 10 pm in diameter and show interpenetrant growth.”

“The structure of boehmite consists of double layers of oxygen octahedra partially filled with Aluminium cations.”

“The groundmass consists mainly of bytownite with large grains of diopside and of colourless olivine, and small octahedrons of magnetite.”

“The cleaning layer has fully reticulated pores in a uniform network of substantially equilateral cells 34, such as tetrahedrons, truncated octahedrons and decahedrons.”

“In the Isometric Tribe can be found the families of the Tetrakis Hexahedrons and Octahedrons, with their various descendants.”
