| The Lennard-Jones potential has been known to form either [[Building up an hexagonal close packing structure |hexagonal close-packed]] (hcp) or [[Building up a face centered cubic lattice |face-centred-cubic]] (fcc) structure. <ref>[http://dx.doi.org/10.1063/1.4955061 Hertanto Adidharma and Sugata P.

| Recently it has been shown that the ground state structure strongly depends on [[pressure]], cutoff radius and the potential truncation method; and stacking sequences (polytypes) other than fcc and hcp can be the ground state structure too, e.g. dhcp, 9R...etc.
