We study the densest lattice packings that can be built up in layers. Start with the 1-dimensional lattice Λ1 of even integer points; at the nth step stack layers of a suitable (n − 1)-dimensional lattice Λ n − 1, as densely as possible, keeping the same minimal norm; the result is a laminated lattice Λ n . In this chapter the density of Λ n is determined for n ≤ 48, all Λ n are found for n≤ 25, and at least one Λ n is found for 26 ≤ n ≤ 48. The unique Λ24 is the Leech lattice. Denser lattices than Λ n are now known for n ≥ 30.
