Don't they just have to not be parallel?

• Retric 13y ago
  No, your thinking 2D lines, but this is 3D space. It's easy to arrange things so they all miss each other and not have them be parallel. The goal is to have them touch, but not intersect.
• anon4 13y ago
  Nah, not quite. You want every cylinder touching all 6 other cylinders and not going through them.

  In three dimensions, non-parallel lines do not necessarily intersect.
• lcnmrn 13y ago
  Yes, if the radius is infinite. But I think this is not the case.
