Sažetak
A Frank-Kasper structure is a 3-periodic tiling of the Euclidean space E^3 by tetrahedra such that the vertex figure of any vertex belongs to 4 specified patterns with, respectively, 20, 24, 26, 28 faces. Frank-Kasper structures occur in the crystallography of metallic alloys and clathrates. A new computer enumeration method has been devised for obtaining Frank-Kasper structures up to 20 cells in a reduced fundamental domain. We compared the 84 obtained structure with the known 27 physical structures and the known special constructions by Frank-Kasper-Sullivan, Shoemaker- Shoemaker, Sadoc-Mosseri and Deza-Shtogrin.
