It would help to say what a lattice is, and how the odd members of the family fail to qualify. I'd also change "It" to something like "the analogous packings", assuming that the D7+ packing (the antecedent of 'it') does not become a lattice when embedded in 8space. —Tamfang (talk) 21:36, 29 July 2012 (UTC)
- Agreed, wording and definitions need more clarity. Conway calls them packings. So all the uniform honeycombs (or extended symmetry unions) make equal-sphere packings, but lattices are the subset that can be expressed by simple translational symmetry of the lattice points.
