DIAMOND is the colloquial name for the consortium of spaceships in orbit around a gas giant in the Württemberg sector.  Each ship is joined to its neighbors by flexible connections between their respective airlocks.  Members come and go fairly frequently, so the lattice-like structure of the Diamond is always changing.  Regulations on intership commerce, taxation, and welfare are controlled by a small council whose members are elected democratically on a rotating basis.  Political campaign advertisements are common, and when adjacent ships share common sentiments, they can create signage that covers several ships in sequence.  An example is: "Seniors Here / Have Done Their Parts / Vote for Tupper / Save Old Farts / Burma-Shave".  The meaning of the last portion of the verse has been lost to history.
