3-D system map

[dodike]

Yes, a tetrahedron has 4 vertices. But New York is basically the center of Sirius, plus it has(in Vanilla anyway) 4 jumpgates leading out of it - Colorado, California, Texas, Alaska.
Furthermore, not only is the Alaska link -hugely- stretched out on the map, it leads to an even -more- stretched out jumphole to Omicron Minor. That implies to me that that particular link is actually going more or less vertical as regards the map, and the link was stretched to make everything fit together on a 2-D plane.

I would still prefer if it was discovered that NY is the center of universe only in 2D projection of the Sirius map while in fact being on a vertex like any other of the vanilla houses. You could still fit 3 gates at the edges of the tetrahedron and the Alaska one going outside of it.
