Integer lattice

Lattice group in Euclidean space whose points are integer n-tuples

In mathematics, the n-dimensional integer lattice, denoted ⁠⁠, is the lattice in the Euclidean space ⁠⁠ whose lattice points are n-tuples of integers. The two-dimensional integer lattice is also called the square lattice, or grid lattice. ⁠⁠ is the simplest example of a root lattice. The integer lattice is an odd unimodular lattice.
