lattice

1. A flat panel constructed with widely-spaced crossed thin strips of wood or other material, commonly used as a garden trellis.
2. A bearing with vertical and horizontal bands that cross each other.
3. A regular spacing or arrangement of geometric points, often decorated with a motif.
4. A model of the tuning relationships of a just intonation system, comprising an array of points in a periodic multidimensional pattern.
5. A discrete subgroup of Rⁿ which is isomorphic to Zⁿ (considered as an additive group) and which spans the real vector space Rⁿ.
6. A discrete subgroup L of a given locally compact group G whose quotient space G/L has finite invariant measure.
7. A finitely generated R-submodule of V which spans V over F. (In this case the submodule is called an R-lattice).
8. A partially ordered set in which every pair of elements has a unique supremum and a unique infimum.
