Point Lattices

Point lattices are regularly spaced arrangements of points. In other words, they are discrete subgroups of Euclidean space. Wolfram|Alpha can be used to compute properties of and compare lattices, root lattices and other kinds of structures that are similar to lattices, such as packing structures.
