Thats interesting, though article is highly speculative. Such packing does occur with atomic matter, I am reminded of Bowen's reaction series where pressure and temperature changes the silicates (tetrahedra) in rocks to octahedra, chains, sheets and framework forms incorporating ions that fit into increasing density.

That article suggests the quarks within the neutron deform into cubic symmetry, though it is not down to anything like chemical bonding, but due to chromodynamics within the neutron, but the neutrons are still unbound.
