(crystallography) The constant distance between unit cells in a crystal lattice. It may be different in each direction, thus a crystalline substance may have up to three lattice constants.

plural of lattice window

(mathematics) Any of the 24 positive definite even unimodular lattices of rank 24.

(mathematics) An even unimodular lattice Λ₂₄ in 24-dimensional Euclidean space, which is one of the best models for the problem of finding the maximum possible kissing number for n-dimensional spheres in (n + 1)-dimensional Euclidean space.

(crystallography) A regular three-dimensional geometric arrangement of atoms, molecules or ions in a crystal

(graph theory) A kind of connected cycle-free graph.

(geometry, crystallography) An infinite array of discrete points generated by a set of discrete translation operations mathbf R=n_1 mathbf a₁+n_2 mathbf a₂+n_3 mathbf a₃, where nᵢ are any integers and aᵢ are known as the primitive vectors which lie in different directions and span the lattice.
