Also known as Cannonball lattice.
Description
Laminated three-dimensional lattice consisting of layers of hexagonal lattices.
Protection
The \(D_3\) fcc lattice exhibits the densest packing, highest kissing number of 12, and the thinnest lattice covering in three dimensions. The Kepler conjecture [1] states that the \(D_3\) fcc lattice has the densest packing in 3D.
It was first proven that this lattice was the densest 3D lattice packing [2]. Determining the maximum density of any sphere packing in 3D was then reduced to a computationally tractable problem [3], which was solved [4] and formalized in automated proof checking software [5].
Parent
- \(D_n\) checkerboard lattice — The \(D_3\) root lattice is equivalent to the \(A_3\) root lattice [6; Ch. 10].
Cousins
- Body-centered cubic (bcc) lattice — The bcc and fcc lattices are dual to each other.
- Cubeoctahedron code — Cubeoctahedron codewords form the minimal shell of the \(D_3\) face-centered cubic (fcc) lattice.
